Stand took Lily to his friends restaurant on a date. The friend told the waiter to remove the $12 dessert from Stans 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.

Question

_ ( b - ) = _

Answer 1

To determine the amount of the original bill, \( b \), we can set up the equation based on the information provided.

1. The dessert that was removed was $12, so the reduced bill is \( b - 12 \).
2. Stan tipped 20% of the reduced bill, which amounts to $15.

The equation can be set up as follows:

\[ 0.20 \times (b - 12) = 15 \]

Now let's fill in the blanks:

\[ 0.20 ( b - 12 ) = 15 \]

This equation can be solved for \( b \) to find the original bill amount.
