Reasoning and answer: Let the number of chickens be c. If there are 150 ducks, we can describe the number of chickens as 150 = 10 + 4c. So, 4c = 150. And, there are c = 35 chickens. In total, Jen has 35 chickens + 150 ducks = 185 birds.
The answer: 185

Question: Jen has 10 more ducks than four times the number of chickens. If Jen has 150 ducks, how many total birds does she have?
Larry's shoulder height is 20% less than 5 feet, or 0.2 * 5 = 1 foot less than 5 feet. One foot less than 5 feet is 5 - 1 = 4 feet. If Barry stands on Larry's shoulders, they can reach 4 + 5 = 9 feet.
The answer: 9
Reverse engineering the question: Larry and Barry want to pick apples out of the tree, but neither is tall enough to reach the apples. Barry can reach apples that are 5 feet high. Larry is 5 feet tall, but his shoulder height is 20% less than his full height. If Barry stands on Larry's shoulders, how high can they reach?
Reasoning and answer: Before going on vacation, Grandpa counts 36 tomatoes. After going on vacation, Grandpa has 100 * 36 = 3600 tomatoes. So in his absence, 3600 - 36 = 3564 tomatoes have grown.
The answer: 3564

Brad weighs 145 + 5 = 150 pounds. Billy weighs 150 + 9 = 159 pounds.
The answer: 159
Reverse engineering the question: Billy weighs 9 pounds more than Brad. Brad weighs 5 pounds more than Carl. If Carl weighs 145 pounds, how much does Billy weigh, in pounds?
Reasoning and answer: She sold 5 necklaces at $25.00 apiece for a total of 5 * 25 = $125.00. She sold 10 bracelets for $15.00 each for a total of 10 * 15 = $150.00. She sold 20 earrings for $10.00 a pair for a total of 20 * 10 = $200.00. She sold 2 ensembles for $45.00 each for a total of 2 * 45 = $90.00. All total she made 125 + 150 + 200 + 90 = $565.00.
The answer: 565

Reasoning and answer: He spends $10 / snake * 4 snakes = $40 to feed his snakes every month. He spends $5 / iguana * 2 iguanas = $10 to feed his iguanas every month. He spends $15 / gecko * 3 geckos = $45 to feed his geckos every month. So overall he spends $40 + $10 + $45 = $95 to feed all his pets every month. Therefore every year pet food costs him $95 / month * 12 months = $1140.
The answer: 1140
