Answer 1

Given,

A car averages 27 miles per gallon.

The gas cost is $4.04 per gallon.

To find: The cost of the gas.

Solution:

We are given the ratio

$1\text{ gallon : 27 miles }$

Which can also be written as

$\frac{1\text{ gallon}}{27\text{ miles}}$

Travelling 2,727 miles at a ratio of

$\frac{1\text{ gallon}}{27\text{ miles }}$$2,727\text{ miles}\times\frac{1\text{ gallon}}{27\text{ miles}}=101\text{ gallons}$

At a cost of $ 4.04 per gallon.

This would cost

$\frac{4.04}{gallon}\times101\text{ gallons=408.04}$

Thus, the given option (c) is correct.
