Q: Jerusha earned 4 times as much money as Lottie. Together they earned $85. How many dollars did Jerusha earn? Use L to represent Lottie's earnings.
A: L = Lottie's earnings. Jerusha's earnings = 4L. L + 4L = 85. L = 85 / 5. L = 17 so Jerusha earned 4L = 4(17) = 68. Jerusha earned $68. The answer is 68.

Q: In a card game, you are awarded 10 points if you win one round. While playing, Jane ends up with 60 points. If she lost 20 points, then how many rounds did she play?
A:
If Jane got 60 points and lost 20 points then the total number of points she accumulated in all the rounds was 60 + 20 = 80 points. If each round is awarded 10 points, then the number of rounds will be 80 / 10 = 8 rounds. The answer is 8.
