Please, someone help me, I am using conversions for this!

Sarah wants to buy the car that has a better mileage rating. Cars of Company A
travel 20 miles per gallon and cars of Company B travel 14 km per liter.

[1 mile=1.6km; 1 gallon=3.79 liters]

Part A: Which company's car should Sarah buy? Justify your answer by comparing the mileages after converting to the same units.

Part B: If 10 gallons of gas is filled in the car which gives better mileage, and you went on a drive and checked on the gas used every 30 miles, describe the appropriate scales on the x-axis and y-axis to graph the rate at which the car uses gas.

car 1 : 20 miles/gallon
car 2 : 14 km/liter

conversion to km/liter
car 1 : 20 miles x 1.6km /3.79 liters = 32 km/3.79 liters = 8.4 km/liter
choose car 2
