A family has two cars. The first car has a fuel efficiency of 40 miles per gallon of gas and the second has a fuel efficiency of 35 miles per gallon of gas. During one particular week, the two cars went a combined total of 1525 miles, for a total gas consumption of 40 gallons. How many gallons were consumed by each of the two cars that week?

Hmmm. This question is tricky but all I can say is that since there is a combined total of the miles and they don't say the certain amount of miles each gallon gives. You might wanna try and figure out the amount of miles each gallon gives you.
