A company charges $10 for shipping and $7 per shirt.

Which equation below can be used to solve for the

number of shirts ordered for an order that costs $52?

a) 52 = 10x + 7

b) 52 = 7x - 10

c) 7x + 10 = 52

d) 52x + 10 = 7

A. 52=10x+7X=9/2=4.5

Step-by-step explanation:

10x+7=52 (Switch sides.)

10x+7-7=52-7 (Subtract 7 from both sides.)

52-7 (Solve.)

52-7=45

10x=45

10x/10=45/10 (Divide by 10 from both sides.)

45/10 (Solve & simplify.)

45/10=9/2

x=9/2=4.5

So, the correct answer is (A.) 52=10x+7 and x=9/2=4.5.

Answer: C. $52 = 10 + 7x
