Part A
What is the size of the SUV’s tank in gallons? Round your
answer to the nearest whole number.
Part B
At the destination, there was a quarter-tank of gas left in the vehicle and the
miles were recorded as 24,297. Use a ratio equation to determine the gas mileage
in miles per gallon for the trip. Round your answer to the nearest whole number.
Part C
Two months later, the Jensen family takes their mom’s sedan
on a different trip. When she fills the tank, Sally’s mom records
the miles on the sedan as 15,004. It takes $71.98 to fill up the
vehicle’s empty gas tank. What is the size of the sedan’s tank in
gallons? Round your answer to the nearest whole number.
Part D
At one point on the trip, the miles are recorded as 15,121 when the gas tank is
75% full. Use a ratio equation to determine the miles per gallon the sedan
averages. Round your answer to the nearest whole number.
Part E
Which vehicle has the better gas mileage? Explain your reasoning.
