Question

A traveling salesman figures it costs  cents for every mile he drives his car. How much does it cost him (in dollars) a week to drive his car if he travels  miles a week?

Answer 1

We know it costs the salesman 27 cents or $0.27 to drive his car per mile.

If he drives 390 miles, we must simply multiply the numbers together.

($0.27/mile) * (390 miles) = $105.30
