Question

Stan took Lily to his friend’s restaurant on a date. The friend told the waiter to remove the $12 dessert from Stan’s bill. Stan tipped the waiter 20% on the reduced bill, which was a $15 tip. Fill in the blanks to write an equation that will determine the amount of the original bill, b .(2 points)

Answer 1

Let the original bill amount be b.
After the friend removed the $12 dessert, the reduced bill amount was b - 12.
Stan tipped the waiter 20% on the reduced bill, which was 0.20 * (b - 12).
The equation that determines the amount of the original bill is:
b - 12 + 0.20 * (b - 12) = b.
