Question

Hi! I have a math question. This is a two part problem.

This is the first question which I already found the answer to:
"Blair is ordering 150 T-shirts to sell at the school carnival. Company A charges $3 for each shirt, plus 6% of the total order for shipping. Company B charges $3.10 per shirt, plus 4% of the total order for shipping. Company C charges $3.20 per shirt with no shipping fee. Question 1 Part A Drag a company name into each box to show the total costs from least to greatest. Least Cost Greatest Cost
A. Company B. Company C. Company" The answer was A,C,D.
The next part is the screenshot. Thank you!

Answer 1

Blair chosen to purchase shirt from company B. Given:

Each shirt costs 3.10$

Shipping cost is 4% (0.04) of total order.

=>Total cost without shipping: 150 x 3.10 = 465$

=> Total cost with 4% of shipping: 465 + 465 x 0.04 = 483.6$

=> Total cost Blair paid for one shirt: C = 483.6/150 = 3.22$

The markup is 75% of original cost:

=> Blair can multiply the total cost for one shirt by 0.75

Blair will sell shirt with price which is equal to the sum of total cost for one shirt and markup:

=> P = 3.22 + 3.22 x 0.75 = 5.64$

Hope this helps!
