If Cool Shirts offered a deal for free shipping, how many shirts would you need to purchase until the companies cost the same? CORRECT ANSWER GETS BRAINLEY ANSWER QUICKK!!

32 shirts

Step-by-step explanation:

Charges of x shirts by Cool Shirts = 8x + 13

(shipping of shirts = $13)

Charges of x shirts by Total Tees = 7.5x + 16

(Shipping of shirts = $16)

If Cool Shirt offered a deal of free shipping (Shipping = 0),

Charges of x shirts by Cool shirts = 8x

Total charges from both the companies will be equal if,

8x = 7.5x + 16

8x - 7.5x = 16

0.5x = 16

x = 32

Therefore, purchase of 32 shirts will be needed until companies cost the same.

b

step-by-step explanation:

a difference is the result of subtraction. while each of these expressions has subtraction in it, a difference will be the result when subtraction is the last operation applied in the order of operations for the expression. this means subtraction must be outside of the parenthesis. only b has this.
