Q: Rodney, Roger and Ron can lift a combined weight of 239 pounds. Rodney can lift twice as much as Roger, and Roger can lift 7 pounds less than 4 times the amount that Ron can lift. How much can Rodney lift?
A: Let x represent the amount that Ron can lift. Roger: 4x - 7. Rodney:2(4x - 7) = 8x - 14. Total:x + 4x - 7 + 8x - 14 = 239. 13x - 21 = 239. 13x = 260. x = 20. Rodney:8(20) - 14 = 146 pounds. The answer is 146.

Q: Ajax is 80 kilograms. He is planning to lose some weight. Exercising for an hour will help him lose 1.5 pounds. If 1 kilogram is equal to 2.2 pounds How many pounds will he weigh if he exercises for 2 hours every day for two weeks?
A: Ajax weighs 80 x 2.2 = 176 in pounds. He will lose 1.5 x 2 = 3 pounds per day. So he will lose 3 x 7 = 21 pounds per week. So, he will lose 21x 2 = 42 pounds after 2 weeks. Therefore, he will weigh 176 - 42 = 134 pounds after 2 weeks. The answer is 134.
Question: Melody has three dogs. Each dog eats 1/2 of a pound of dog food twice a day. If Melody bought 30 pounds of dog food, how many pounds of dog food are left after a week?
Answer:
Each dog eats 1 / 2 x 2 = 1 pound of dog food each day. So the three dogs eat a total of 1 x 3 = 3 pounds each day. That is 3 x 7 = 21 pounds in a week. Therefore, 30 - 21 = 9 pounds of food are left after a week. The answer is 9.
