Question

Michael's car can travel 25 miles on one gallon of gas. The cost of gas is $3.75 per gallon. Which equation would calculate the total cost of gas, t, based on the number of miles traveled, n?

Answer 1

`t = (3.75n)/(25)`

Answer 2

Given that, Michael's car can travel 25 miles on one gallon of gas.

Suppose, Michael's car travel 50 miles , then
`(50)/(25)` gallon of gas would be required.

And if Michael's car travel n miles, then
`(n)/(25)` gallon of gas would be required.

We have been given that The cost of per gallon gas is $3.75

then, Cost of
`(n)/(25)` gallon of gas = $
`3.75 * (n)/(25)` .

Hence, The equation that would calculate the total cost of gas, t, based on the number of miles traveled, n is

`t = 3.75 * (n)/(25)`
