A man paid $42.30 for gasoline in May, $38.60 in June, and $43 in July. What was his average monthly cost for gasoline?

Answer 1

To find the average monthly cost for gasoline, we first need to sum the total amounts paid over the three months and then divide this by the number of months.

1. Calculate the total amount paid: \[ 42.30 + 38.60 + 43.00 = 123.90 \]

2. Divide by the number of months (which is 3): \[ \text{Average} = \frac{123.90}{3} = 41.30 \]

Thus, the average monthly cost for gasoline is $41.30.
