Q: Following her doctor’s recommendation to up her daily water intake, Nancy now drinks the equivalent of 60% of her body weight in water. If Nancy’s daily water intake is 54 pounds, how much, in pounds, does she weigh?
A: Let Nancy’s weight be x. We know that 60 / 100 * x = 54 pounds. This translates to x = 54 * 100 / 60 = 90 pounds. The answer is 90.
Question: Ruby was going to order pizza for dinner. Her son would only eat pepperoni pizza. Her daughter would only eat sausage. Ruby and her husband wanted black olive and mushroom pizza. To make life easy, Ruby decided to order an entire pizza for each of her children and she would split one with her husband. The pizza restaurant charged $10.00 per pizza and $1.00 per topping. She also needed to add a $5.00 tip. Including tip, how much would the pizza order cost?
Answer: Ruby was going to order 1 for her son, 1 for her daughter and 1 to share with her husband. So she needed to order 1 + 1 + 1 = 3 pizzas. Each pizza cost $10 and she was ordering 3 so that comes to 10 * 3 = $30.00. She needed to order pepperoni, sausage, black olive and mushroom, which came to 4 toppings at $1.00 each so 4 * 1 = $4.00 extra for toppings. The pizzas cost $30 and $4 for the toppings so the total costs of the pizzas came to 30 + 4 = $34.00. She also had to add a $5.00 tip to her current order total of $34.00 so 5 + 34.00 = $39.00 for the total order. The answer is 39.
[Question]It takes a butterfly egg 120 days to become a butterfly. If each butterfly spends 3 times as much time as a larva as in a cocoon, how long does each butterfly spend in a cocoon?
[Answer]Let c be the amount of time the butterfly spends in a cocoon and l be the amount of time it spends as a larva. We know that l = 3c and l + c = 120. Substituting the first equation into the second equation, we get 3c + c = 120. Combining like terms, we get 4c = 120. Dividing both sides by 4, we get c = 30. The answer is 30.
Q: Sidney does 20 jumping jacks on Monday, 36 on Tuesday, 40 on Wednesday, and 50 on Thursday. Brooke does three times as many jumping jacks as Sidney. How many jumping jacks did Brooke do?

Question: Each week Jaime saves $50. Every two weeks she spends $46 of her savings on a nice lunch with her mum. How long will it take her to save $135?
Answer: Jamie saves 50 * 2 = $100 every two weeks. After the lunch with her mum, Jamie saves $100 - $46 = $54 every two weeks. Jamie saves $54 / 2 = $27 per week. Jamie will need 135 / 27 = 5 weeks to save enough. The answer is 5.
Q: Jason is tired of the neighborhood animals raiding his trash. He pepper-sprays some raccoons and 6 times as many squirrels. If he pepper-sprays 84 animals total, how many raccoons does he pepper-spray?
A:
Let r be the number of raccoons Jason pepper - sprays and s be the number of squirrels. We know that r + s = 84 and s = 6r. Substituting the second equation into the first equation, we get r + 6r = 84. Combining like terms, we get 7r = 84. Dividing both sides by 7, we get r = 12. The answer is 12.
