Question

Answer 1

Answer: Dale will use 13.125 gallons

in the next 100,000 miles

Explanation:

Dale's car uses one quart of oil for every four tanks of gas.

I quart = 0.25 gallon

Therefore,

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 gallons

Number of tanks in 3571.43 will be

3571.43/17 = 210.1 tanks

The car uses 0.25 gallon of oil for 4 tanks, then

The car will use x gallons for 210. 1 tanks.

x =( 210×0.25)/4 = 13.125 gallons
