Question

One week, Kerry travels 125 miles and uses 5 gallons of gasoline. The next week, she travels 175 miles and uses 7 gallons of gasoline. Which best describes the function that can be used to represent m, the number of miles traveled, and g, the number of gallons used?

Answer 1

First find out how much in that one week, the amount of miles per gallon

125/5 = 25, or 25 mpg

Find out how much for the next week

175/7 = 25, or 25 mpg

Note:
g = gallons
m = miles

you're equation will be:
m = 25(g)

For every gallon (g), you multiply it by 25 to get miles (m).


hope this helps
