Question

Randy can buy 6 gallons of gas for $18 or 7 gallons of gas for $21. How much do you think he would pay for 8 gallons of gas?

Answer 1

24 dollars becuase you have to find the price of one gallon and that was 3 so multiply that by 8

Answer 2

By dividing the price per gallon, we see that for every gallon he pays three dollars.
18 Dollars/ 6 Gallons=3 and 21 Dollars/7 Gallons= 3.
So for 8 Gallons, if he pays that same rate of 3 Dollars, he will pay $24.
