Answer:
32 galloons of gas.
Step-by-step explanation:
In one tank, Carol's car can travel 300 miles.
There are 12 gallons in each tank.
She will be travelling 800 miles.
Let "n" be the number of tanks required. So,
[tex](300)(n) = 800[/tex]
[tex](n) = \frac{800}{300} = \frac{8}{3} [/tex]
Thus, the number of galloons is given by,
[tex]\frac{8}{3}(12) = 32 galloons[/tex]
Thus, Carol's car will require 32 galloons of gas to travel 800 miles for visiting her grandmother.
