Stan took lily to his friends restaurant on a date the friend told the waiter to remove the $12 desert from stabs bill Stan tipped the waiter 20 percent 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.

Answer 1

Let's assume that the original bill amount is represented by b.

According to the given information, the friend told the waiter to remove the $12 dessert from Stan's bill. This means that the original bill is reduced by $12, so the new bill amount becomes b - $12.

Next, it is mentioned that Stan tipped the waiter 20 percent on the reduced bill, which was a $15 tip. This can be represented as:

0.2 * (b - $12) = $15

Therefore, the equation that will determine the amount of the original bill b is:

0.2 * (b - $12) = $15
