Phil filled up the 20 gallon gasoline tank in his car for $57.78 what was the cost per gallon of gasoline

Anna H.

The answer isn’t 2.889 cause it needs to be to the nearest penny but the online class says it’s wrong

Cost per gallon = cost/gallon = $57.78/20 = $2.889/gallon

While $2.889 may seem like an incorrect price for a gallon of gas (why not round to $2.89?), gas prices really are to the tenth of a cent (or thousandths of a dollar). When you see $3.25 on the sign, you are really paying $3.259 (nope, not $3.249 rounded up) for a gallon of gas. Some stations will advertise it this way.
