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

$t = \frac{3.75n}{25}$

Answer 2

Solution :

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

Suppose, Michael's car travel 50 miles , then $\frac{50}{25}$ gallon of gas would be required.

And if Michael's car travel n miles, then $\frac{n}{25}$ gallon of gas would be required.

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

then, Cost of $\frac{n}{25}$ gallon of gas = $ $3.75 * \frac{n}{25}$ .

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

$t = 3.75 * \frac{n}{25}$
