Answer

Explanation:

Step1: Sum the known expenses.

Add the amounts spent on oil change, gas, and lunch. $$ $18.95 + $20.50 + $12.68 = $52.13 $$

Step2: Subtract the sum of known expenses from the total amount spent.

The difference represents the amount spent on golfing. $$ $87.33 - $52.13 = $35.20 $$

Answer:

a. $35.20
