Gerald can drive about 516 miles on 12.9 gallons of gas.

To figure out how much 12.9 gallons would cost if we know that it cost $3.95 per gallon, we multiply 12.9 by $3.95.

12.9 × 3.95 = $50.955 or $50.95.

It would cost Gerald about $50.95 to buy 12.9 gallons of gas if it cost $3.95 per gallon.

Hope that helps!
