Q. Roselyn is driving to visit her family, who live 150150 kilometers away. Her average speed is 6060 kilometers per hour. The car's tank has 2020 liters of fuel at the beginning of the drive, and its fuel efficiency is 66 kilometers per liter. Fuel costs 00.6060 dollars per liter.\newlineWhat is the price for the amount of fuel that Roselyn will use for the entire drive?\newline__________dollars\newline
  1. Calculate total distance and fuel efficiency: Calculate the total distance Roselyn will drive and the fuel efficiency to find out how much fuel she will need.\newlineTotal distance = 150150 kilometers, Fuel efficiency = 66 kilometers per liter.\newlineFuel needed = Total distance / Fuel efficiency = 150km/6km per liter=25liters.150 \, \text{km} / 6 \, \text{km per liter} = 25 \, \text{liters}.
  2. Calculate fuel cost: Calculate the cost of the fuel used for the drive.\newlineFuel cost per liter = 0.600.60 dollars.\newlineTotal fuel cost = Fuel needed ×\times Fuel cost per liter = 2525 liters ×\times 0.600.60 dollars/liter = 1515 dollars.
