Question

jason bought 3 shirts that each cost the same. he had a coupon for $10 off and he spent $65 altogether. which equation can be used to find the cost of each shirt.

(3 s +10=65) (10 s+3-65) (3 s -10=65) (10-3 s -65

Answer 1

Let's say s is the price of one shirt. Since we have 3 shirts, we have 3s.

Our coupon for 10 dollars off means we can take 10 off the price of the 3 shirts: 3s-10.

Since 65 is the total amount we spent, 3s-10=65

Hope this helps!
