Answer:13.125 gallons of oil
Explanation:
Dale's car uses one quart of oil for every four tanks of gas.
1 quart of oil = 1/4 gallons of oil
Dale's car uses one quart of oil for every four tanks of gas. This means that he uses 1/4 gallons of oil for every 4 tanks of gas
Mileage of the car is the number of miles travelled by the car with 1 gallon of gas. The car averages 28 miles per gallon. That means its mileage is 28 miles per gallon
Capacity of the tank of the car is 17 gallons of gas
Distance traveled by the car =mileage × the number of gallons of gas
100,000 miles will require 28 × x gallons.
x = 100000/28 = 3571.43 gallons
Number of tanks will be total number of gallons used /number of gallons in one tank. It becomes
3571.43 / 17 = 210.1 tanks
1/4 gallons of oil is used for 4 tanks
y gallons of oil will be used for 210 tanks
y = (1/4 ×210)/4 = 13.125 gallons of oil
