A new compact car can travel 288 miles on nine gallons of gas. The distance driven in miles y varies directly with the number of gallons of gas x. This situation can be represented by the equation y = 32x.

Answer:

Explanation of why
y = 32x is correct.

Explanation:

The number of miles that the car can drive can be written as a function of the number of miles that each gallon is capable of by this following function:


y = ax

In which a is the number of miles each gallon runs.

A new compact car can travel 288 miles on nine gallons of gas. How many miles can it travel on one gallon? This can be solved by a rule of three.

288 miles - 9 gallons

a miles - 1 gallon


9a = 288


a = 32

So

y = 32x is a correct representation for this problem, since with each gallon of gas the car can run 32 miles.
