OPTION 1: 6s - 15 = 45
OPTION 2: 6s + 15 = 45
OPTION 3: 6s - 45 = 15
OPTION 4: 6s + 45 = 15

Answer 1

The correct equation for the cost of one t-shirt with the given discounts and total spent is 6s - 15 = 45.

Step-by-step explanation:

The student has presented a situation where Kaylee bought 6 t-shirts, used a $15 off coupon, and spent a total of $45. To find the equation representing the cost of one t-shirt, let s represent the cost of one shirt. We start by multiplying the cost of one shirt by the number of shirts bought, 6, and then we subtract the value of the coupon. Finally, we set this equal to the total amount spent.

The correct equation that represents this situation is Option 1: 6s - 15 = 45. This equation indicates that after buying 6 shirts and applying the $15 coupon, Kaylee's total expenditure was $45.
