Victor needs to calculate the number of miles per gallon his car averages. His car's gas tanks holds 15 gallons of gas. Write an equation that will help him determine the average number of miles per gallon. Let's let x= number of miles traveled, and y= average miles per gallon. I thought that it was 15y=x
Since you're looking for the unit rate, you can start do this: [tex]mpg= \frac{miles}{gallon}\\
y=\frac{x}{15}[/tex] And yes, [tex] 15y=x [/tex] is also correct, it's just switching around the 15
