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.

Answer 1

To find the reduced bill, we need to subtract the tip from Stan's total bill.

Let's assume the total bill after the dessert was removed is 'x'.

So, Stan tipped the waiter 20% of 'x' which is equal to $15.

This can be represented as:

0.2 * x = $15

Multiplying both sides of the equation by 10 to get rid of the decimal:

2x = $150

Dividing both sides of the equation by 2:

x = $75

Therefore, the reduced bill after removing the dessert was $75.
