Answer:

$34.88

Step-by-step 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).
