A department store buys 100 shirts at a cost of $2,400 and sells them at a selling price of $30 each.
Find the percent markup.
Answer:
There is a 25% markup
Step-by-step explanation:
First find the original cost of each shirt
$2400/ 100 shirts
$24/ shirt
Mark up = ( new price - original price) / original price
= ( 30-24) / 24
= 6/24
= 1/4
= .25
25%
There is a 25% markup
Answer:
percent markup = 25%
Step-by-step explanation:
buys 100 shirts = $2400
buys 1 shirt = $2400/ 100
= $24
sells 1 shirt = $30
percent markup:
=[ ( selling price - bought price) ÷ bought price ] × 100
= [ (30-24) ÷ 24 ] × 100
= [ 6 ÷ 24 ] × 100
= 0.25 × 100
= 25 %

Step-by-step explanation:
Johanna took $125 to the mall. She bought 5 shirts (s) that cost the same price. Which expression represents the amount of money, in dollars, that Johanna had after she bought the shirts?
Answer:
I think its something like: Money Leftover = 125 - (price of one shirt * 5)
Step-by-step explanation:
just use variables in the place of "price of one shirt" and "Money Leftover".
multiplying the price of one shirt by five since she buys 5 of the same shirt and subtracting that value from her budget will leave you with the amount of money she had left after the purchase.
Answer:
125-5s=money left over (s is the price of one shirt)

Answer:
-7/4 < x < 8
Step-by-step explanation:
The value of y can be determined from the sum of the angles, so you know each of the angles exactly. That means you know the ratio of side lengths exactly, which lets you solve for x exactly.
__
Setting that aside, we observe that angle C is greater than angle A, so side AB will be longer than side BC.
3x +15 > 4x +7
8 > x . . . . . . . . . . subtract 3x+7
We also know that the lengths of these sides must be positive. Since BC is the shorter side, we require ...
4x +7 > 0
4x > -7
x > -7/4
So, the allowable values of x are ...
-7/4 < x < 8
_____
More complete solution
If we read the figure correctly, the sum of angles is ...
(2y +12) +(4y +12) +(y -18) = 180
7y +6 = 180
y = (180 -6)/7 = 24 6/7°
Then (in degrees) ...
∠A = 2(24 6/7) +12 = 61 5/7, and ∠C = 4(24 6/7) +12 = 111 3/7
The Law of Sines tells us ...
AB/sin(C) = BC/sin(A)
sin(A)(3x +15) = sin(C)(4x+7)
x(4sin(C) -3sin(A)) = 15sin(A) -7sin(C)
x = (15sin(A) -7sin(C))/(4sin(C) -3sin(A))
x ≈ 6.1872652

A self-service car wash has 3 individual car wash stalls. Customers wait in a single line before choosing the next available stall. 33 customers enter the car wash per hour and it take 5 minutes for each customer to wash their car. Customer arrivals and service times follow an exponential distribution. What type of queuing model is this process?
Answer:
single-channel, multi -phase
Step-by-step explanation:
The concept known as '' Queuing'' is not only important in the mathematical aspect alone but it is also useful in economic matters as signifies the abundance of resources that is when we have queues it means the reason for it is that the available resources is not enough.
From the question above we have that there are 3 individual car wash stalls, it is also given that the customers wait in a single line before choosing the next available stall. This means that there is only a single-channel.
Then, we have that from the single line initially, the queues then moves to multi -phase that is to 3 individual car wash stalls.

Step-by-step explanation:
f(x)=3x+3, then f^-1(x)=
Answer:
f^ - 1 (x) = x/3 + 1/3 is not the inverse function of f(x) = 3x + 1
Step-by-step explanation:
F(x) = 3x + 1
Inverse:
x = 3y + 1
3y = x - 1
y = x/3 - 1/3 or f^ - 1 (x) = x/3 - 1/3
so
f^ - 1 (x) = x/3 + 1/3 is not the inverse function of f(x) = 3x + 1
Simplify (x - 4)(3x^2- 6x + 2).
Answer:
3x³ - 18x² + 26x - 8
Step-by-step explanation:
(x - 4)(3x²- 6x + 2) =
= x*3x² + x*(- 6x) + x*2 + (-4)*3x² + (-4)*(-6x) + (-4)*2
= 3x³ - 6x² + 2x - 12x² + 24x - 8
= 3x³ - 18x² + 26x - 8

A password hash function is applied 12 times to secure a password. If it takes 21 minutes to brute force one application of the hash with the available resources, how long will it take to brute force the password if the available resources are quadrupled.?
a. 21 minutes
b. 63 minutes
c. 210 minutes
d. none of the above.
Answer:
b. 63 minutes
Step-by-step explanation:
Given;
number of times the hash function is applied = 12
time taken to brute force one application, = 21 minutes
Apply proportion, bearing in mind that 4 available resources should take less time;
1 available resource ------- 21 minutes
4 available resources ------ x
Thus, x = 21 minutes / 4
When applied 12 times, the time should be [tex]\frac{21 \ minutes}{4} \ \times \ 12 \ = 63 \ minutes \\\\[/tex]
Therefore, the correct option is B, 63 minutes

[tex]\mathrm{Apply\:exponent\:rule}:\quad \frac{x^a}{x^b}\:=\:x^{a-b}[/tex]

Answer:
7 : 11 is the right answer
A retailer marks his price 10% above cost, another retailer arranges his
price so that he will have a profit of 20% on his returns. If the
manufacture's price for an article is Rs. 50, what is the difference
between the retailers selling prices? What percent discount should the
retailer with higher price give, so that the profit would be equal?
Answer:
The answer is below
Step-by-step explanation:
The cost price (manufacturing price) of an article is Rs.50.
Retailer 1 marks his price 10% above cost, hence the selling price for retailer 1 is:
Selling price for retailer 1 = 10% of Rs.50 + Rs.50 = (0.1 * Rs.50) + Rs.50 = Rs.55
Retailer 2 sets a profit of 20% on his returns, hence the selling price for retailer 2 is:
Selling price for retailer 2 = 20% of Rs.50 + Rs.50 = (0.2 * Rs.50) + Rs.50 = Rs.60
The difference between the retailers selling prices = Rs.60 - Rs.50 = Rs.10
The retailer with the highest price sells for Rs.60 and the difference between the retailers selling prices is Rs.10. For the profit to be equal, the percentage discount is:
Discount = (Rs.10 / Rs.60) * 100% = 16.67%

Answer:
50. B51. -3x + y = 11Step-by-step explanation:
50......................................................................
Parallel lines have equal slopes.
Converting the given into slope-intercept form:
2x + 3y = 153y = -2x + 15y = -2/3x + 5Option B is the parallel line with different y-intercept
51.......................................................................
Perpendicular lines have negative reciprocal slopes.
Converting the given into slope-intercept form:
x + 3y = 153y = -x + 15y = -1/3x + 5Perpendicular line will have a slope of
m*(-1/3) = - 1 m = 3The equation will be:
y = 3x + bto find b using the given point (-2. 5)
5 = 3*(-2) + b5 = -6 + b5 + 6 = bb = 11So the line is:
y = 3x + 11or
-3x + y = 11 in standard formHelp me with these maths, thanks.
