Answer:
Gerald can drive about 516 miles on 12.9 gallons of gas.
12.9 gallons would cost about $50.95.
Step-by-step explanation:
To know how many miles Gerald could drive, we multiply the miles per gallons by how many gallons Gerald has.
40 × 12.9 = 516
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!
