For example, a business calculates the fuel economy of its delivery truck to be 19 miles per gallon. However, the amount of fuel used on a 20-mile delivery run is four gallons. This means either the calculation is incorrect or the reported usage is incorrect. Solve the following problems. 1. A business sells 390 units of product for an average of $27.99 each. It reports the gross sales are $10,915. Determine if the reported sales figure is correct. 2. Solution An employee drives a delivery vehicle 298 miles in eight hours. He uses 12 gallons of gasoline. He states his car gets 30 miles per gallon. Determine if the employee is correct. 3. A business spent a total of $43.87 on office supplies in one month and has decided to wait one month to pay the charge. The credit account accrues 2 percent interest per month on outstanding balances. The business estimates the finance charge will be $1. Determine if the finance charge is correct.
