Accepted Solution

A:

Answer: Dale will use 13.125 gallons in the next 100,000 milesStep-by-step explanation:Dale's car uses one quart of oil for every four tanks of gas.I quart = 0.25 gallonTherefore, Dale's car uses 0.25 gallon of oil for every four tanks of gas.The car averages 28 miles per gallon and has a fuel capacity of 17 gallons. This means that 1 tank is 17 gallons.In the next 100000 miles If 28 miles = 1 gallon of fuel,100000 miles will require 100000/28 = 3571.43 gallonsNumber of tanks in 3571.43 will be 3571.43/17 = 210.1 tanksThe car uses 0.25 gallon of oil for 4 tanks, thenThe car will use x gallons for 210. 1 tanks.x =( 210×0.25)/4 = 13.125 gallons
