Solving and Reasoning

Question

Carol's car traveled an average of 28 miles per gallon. At that rate, approximately how many miles could she travel on the gas she bought that morning?

Answer 1

The number of gallons purchased is not given. Therefore, we can only write an expression to show how we would get the answer if the missing information were to be actually given.

Let g = number of gallons purchased

Each gallon gives 28 miles, so added fuel would give her 28g miles, in other words, multiply 28 x the number of gallons purchased.
