Question

Samuel orders a video game online for $40.00. He has a 20% discount code,

and the sales tax is 9%. What is the total cost of his order?

Answer 1

$34.88

Explanation:

If the discount is 20%, then the sale price is 80% of the full (original) cost:

0.80($40.00) = $32.

Sam has to pay 9% sales tax on this $32. The total cost of his order would then be 1.09($32) = $34.88. If desired, you could write this as the equivalent $32 + 0.09($32).
