The answer should be 4.5 because they used AT LEAST 32 miles per gallon. So, 144/32=4.5 and since it's AT LEAST 32, 4.5 is the max amount used.

For this case, the first thing we must do is define variables.

We have then:

n: number of gallons

d: distance traveled

r: distance rate per gallons

The equation that relates the variables is given by:

\(n = \frac{d}{r}
\)

Substituting values we have:

\(n = \frac{144}{32}

n = 4.5 gallons
\)

Answer:

The number of gallons of gas they used is:

\(n = 4.5 gallons\)
