Question: Jenny is planning her catering budget for her wedding. She's going to have 80 guests. 3 times as many guests want steak as chicken. If each steak entree costs $25 and each chicken entree costs $18, how much is the total catering budget?
Answer: Let s be the number of guests who want steak and c be the number who want chicken. We know that s + c = 80 and s = 3c. Substituting the second equation into the first equation, we get 3c + c = 80. Combining like terms, we get 4c = 80. Dividing both sides by 4, we get c = 20. Then multiply the number of guests who want chicken by the cost of each chicken entree: 20 guests * $18 / guest = $360. Then triple the number of guests who want chicken to find the number who want steak: 20 guests * 3 = 60 guests. Then multiply the number of guests who want steak by the cost of each steak entree: 60 guests * $25 / guest = $1500. Then add the cost of the steak and chicken entrees to find the total cost: $1500 + $360 = $1860. The answer is 1860.

Q: A fast-food chain offers free delivery for a minimum purchase of $18. Danny ordered 2 quarter-pounder burgers for $3.20 each, 2 large fries that cost $1.90 each, and 2 milkshakes that cost $2.40 each. How much more worth of food should he order to avail of the free delivery?
A: Two quarter - pounder burgers cost $3.20 x 2 = $6.40. Two large fries cost $1.90 x 2 = $3.80. Two milkshakes cost $2.40 x 2 = $4.80. The total amount spent for the burgers, fries, and shakes is $6.40 + $3.80 + $4.80 = $15. Therefore, he should order $18 - $15 = $3 worth of additional food to take advantage of the free food delivery. The answer is 3.
Question: A bear is hunting for her cubs and herself. She needs 210 pounds of meat in a week. Each cub needs 35 pounds a week and she has 4 cubs. She hunts rabbits, which are five pounds each. If she hunts daily, how many rabbits does she need to catch each day?
Answer: The cubs need 140 pounds a week because 4 x 35 = 140. The family needs 350 pounds a week because 210 + 140 = 350. The family needs 50 pounds a day because 350 / 7 = 50. She needs to hunt 10 rabbits a day because 50 / 5 = 10. The answer is 10.

[Question]Joel is 5 years old and his dad is 32 years old. How old will Joel be when his dad is twice as old as him?
[Answer]
The difference in age between Joel and his dad is 32 - 5 = 27 years. When you double this gap in years, you have 27 x 2 = 54. When his dad is 54, Joel will be 54 / 2 = 27 years old. The answer is 27.
