b.
$45.20
c.
$47.88
d.

Answer 1

To find out how much Mario spent on golfing, we can use the total amount he spent and the amounts for the other transactions he has recorded.

1. First, we add up the amounts of the transactions he has recorded:

   • Oil change: $18.95
   • Gas in car: $20.50
   • Lunch out: $12.68

2. Now, let's sum these amounts: \[ 18.95 + 20.50 + 12.68 = 52.13 \]

3. The total amount Mario spent last week is $87.33.

4. Now we can find out how much he spent on golfing by subtracting the sum of the known amounts from the total amount spent: \[ \text{Amount spent on golfing} = 87.33 - 52.13 = 35.20 \]

Thus, Mario spent $35.20 on golfing.

The correct answer is: a. $35.20
