Chevy Silverado

1) In this question, we are going to find the unit rate so that we can get the best relation: mileage/gas

2) Let's start with the 2007 Ford F-150:


\begin{gathered} m------------g \\ 250----------150 \\ x------------1 \\ 150x=250 \\ x=(250)/(150) \\ x=(1.6m)/(g) \end{gathered}

So that Ford F-150 makes 1.6 miles per gallon

b) Chevy Silverado:


\begin{gathered} m-----g \\ 500----29.4 \\ y------1 \\ 29.4y=500 \\ y=(500)/(29.4) \\ y=\frac{17.00m}{\text{gallons}} \end{gathered}

Thus, the Chevy Silverado makes 17 miles per gallon.

c) Toyota Tundra:


\begin{gathered} m-----g \\ 428----26.4 \\ z-----1 \\ 26.4z=428 \\ z=(428)/(29.4)=(14.55m)/(g) \\ z= \end{gathered}

3) Thus the best gas mileage is: Chevy Silverado
