Question: Mona bikes 30 miles each week to stay fit. This week, she biked on Monday, Wednesday, and Saturday. On Wednesday, she biked 12 miles. On Saturday, she biked twice as far as on Monday. How many miles did she bike on Monday?
Answer: Step-by-step reasoning process: Let M be the number of miles Mona biked on Monday. Thus, Mona biked 2M miles on Saturday. In all, Mona biked M + 2M + 12 = 30 miles. Thus, on Monday and Saturday, she biked M + 2M = 3M = 30 - 12 = 18 miles. Therefore, on Monday, Mona biked M = 18 / 3 = 6 miles.
So the answer is 6.

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?
Answer: Step-by-step reasoning process: 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.
So the answer is 9000.

Question: Carol has $60 and saves $9 per week. Mike has $90 and saves $3 per week. How many weeks before Carol and Mike both have the same amount of money?
Answer: Step-by-step reasoning process: Let x = the number of weeks. 60 + 9x = 90 + 3x to set them equal. 9x = 30 + 3x. 6x = 30. x = 5. In 5 weeks they will have equal money.
So the answer is 5.
