Question: Transportation costs include car payments, and costs for gasoline, repairs, etc. What is the average monthly expenditure for transportation costs?
First Compute the Average Monthly Expenditure:
A:). Find the Sum of Monthly Expenditures:
$315.50 + $315.50 + $315.50 + $129.05 + $123.40 + $90.87 + $236.50  $1,526.32 / 3 ============> $508.77333..... =======> $508.77
B:). Take the Sum of the Monthly Expenditures, and Divide by the Number of Months: ======> $1,526.32
Sum of Monthly Expenditures Divided Number of Months: 3
(Jan, Feb, Mar.).
= $1,526.32 / 3
= $508.77333……
The average monthly expenditure for transportation to the nearest cent is:
