April and four of her friends have all decided to go on a diet to see if they can lose a few unwanted pounds before they have to start trying on swimsuits. Each of the five friends has decided to give up their favorite snack food and to start exercising in order to lose weight. Each person wants to lose a different amount of weight.

Friends: Mable, Bob, Mike, April, and Sarah
Snacks: Chocolate, Potato Chips, Ice Cream, Candy, and Pizza
Number of Pounds to Lose: 13, 20, 24, 27, and 34
Exercise: Treadmill, Yoga, Karate, Walking, and Boxing

2. Mable is trying to lose exactly 14 pounds fewer than the person walking.

3. Bob (who is not the one taking Yoga) has stopped eating his afternoon bowl of ice cream. Bob is trying to lose exactly 7 pounds fewer than the boxer.
