To find out how much Mario spent on golfing, let's follow a step-by-step approach:
1. Identify the total amount spent: Mario spent a total of [tex]$\$[/tex]87.33[tex]$. 2. List the known expenditures: - Oil change: $[/tex]\[tex]$18.95$[/tex]
- Gas in car: [tex]$\$[/tex]20.50[tex]$ - Lunch out: $[/tex]\[tex]$12.68$[/tex]
3. Sum the known expenditures:
[tex]\[ 18.95 + 20.50 + 12.68 = 52.13 \][/tex]
4. Calculate the unknown expenditure for golfing: Subtract the sum of the known expenditures from the total amount spent.
