Final answer:
Kevin will pay $120.77 for the ball and shoes, including tax.
Step-by-step explanation:
First, we need to find the total cost of Kevin's purchase before any discounts or taxes. This can be done by adding the prices of the soccer ball and the soccer shoes: $25.00 + $125.50 = $150.50.
Next, we need to calculate the discount Kevin receives using the 25% off coupon. To do this, we multiply the total cost by 25% (or 0.25): $150.50 x 0.25 = $37.63.
Now, we subtract the discount from the total cost to find the discounted price: $150.50 - $37.63 = $112.87.
Finally, we calculate the sales tax by multiplying the discounted price by 7% (or 0.07): $112.87 x 0.07 = $7.90.
Adding the sales tax to the discounted price gives us the final amount Kevin will pay for the soccer ball and shoes, including tax: $112.87 + $7.90 = $120.77. However, none of the options provided match this amount, so it seems like there may be an error in the answer choices.
