Beth has $105 - $35 = $70. Jan has $70 + $10 = $80. So, Beth and Jan have $70 + $80 = $150 altogether.
The answer: 150
Reverse engineering the question: If Beth had $35 more, she would have $105. If Jan had $10 less, he would have the same money as Beth has. How much money do Beth and Jan have altogether?


Reasoning and answer: The dog’s total weight is 150 because 20 + 40 + 10 + 30 + 50 = 150. They need 15 pounds a day because 150 / 10 = 15.
The answer: 15

Question: Paul has five dogs. For every 10 pounds they weigh, they need 1 pound of dog food per day. One weighs 20 pounds. One weighs 40. Another weighs 10. One weighs 30 and the final one weighs 50 pounds. How much dog food does he need each day?


If $44,000 is $1000 less than five times more than he had made on his previous painting, then $44,000 + $1000 = $45,000 is five times what he made on his previous painting. If $45,000 is five times what he made for his previous painting, then he made $45,000 / 5 = $9,000 for selling his previous painting.
The answer: 9000
Reverse engineering the question: Porter is a painter who creates beautiful paintings of wild animals. Most recently, he painted a mural of a pack of wolves standing on a snowy-white mountainside underneath a full moon. He put the painting up for auction and it sold for $1000 less than five times more than he had made on his previous painting. If he received $44,000 for the sale of his most recent painting, how much, in dollars, did he make for selling his previous painting?


Reasoning and answer: Three fewer trumpets than Miles has fingers is 10 - 3 = 7 trumpets. Two more guitars than he has hands is 2 + 2 = 4 guitars. Two more trombones than he has heads is 2 + 1 = 3 trombones. And one fewer French horn than he has guitars is 4 - 1 = 3 French horns. Altogether, Miles owns 7 + 4 + 3 + 3 = 17 musical instruments.
The answer: 17

Question: Miles is a musician. He owns three fewer trumpets than he has fingers, and two more guitars than he has hands. He also owns two more trombones than he has heads, and one fewer French horn than he has guitars. What is the total number of musical instruments that Miles owns?


The cost was 3 * 5 = $15. So he got 20 - 15 = $5 in change.
The answer: 5
Reverse engineering the question: Jack orders 3 sandwiches that cost $5 each. He pays with a $20 bill. How much does he get in change?


Two hours means 2 * 60 = 120 minutes. So in 2 hours, there are with 120 / 15 = 8 groups of 15 minutes. So on average Xavier can score 8 * 2 = 16 goals.
The answer: 16
