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?

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
