Q: Susan loves chairs. In her house there are red chairs, yellow chairs, and blue chairs. There are 5 red chairs. There are 4 times as many yellow chairs as red chairs, and there are 2 fewer blue chairs than yellow chairs. How many chairs are there in Susan's house?
A: 43
Step-by-step reasoning process: The number of yellow chairs is 5 chairs 4 = 20 chairs. The number of blue chairs is 20 chairs 2 chairs = 18 chairs. There are 5 chairs + 20 chairs + 18 chairs = 43 chairs in Susan's house.

Q: At a certain school, 2/3 of the population are females. One-tenth of the males are foreign students. If the school has 300 students, how many students are non-foreign male students?
A: 90
Step-by-step reasoning process: There are 300 x 2 / 3 = 200 females in the school. So, 300 - 200 = 100 are males. Out of the 100 males, 100 x 1 / 10 = 10 are male foreign students. Thus, there are 100 - 10 = 90 non - foreign male students.

Q: Jeremy's uncle gave him $50 to spend on basketball equipment. He bought 5 jerseys that cost $2 each, a basketball that cost $18, and a pair of shorts that cost $8. How much money does Jeremy have left?
A: 14
Step-by-step reasoning process: The cost of the jerseys is 5 jerseys $2 / jersey = $10. The total cost of the jerseys, the basketball, and the shorts is $10 + $18 + $8 = $36. Jeremy has $50 - $36 = $14 left.

Q: James buys $3000 worth of stuff from Amazon. He has to return a TV that cost $700 and a bike that cost $500. He also sells another bike that cost 20% more than the bike he returned for 80% of what he bought it for. He then buys a toaster for $100. How much is he out of pocket for everything?
A: 2020
Step-by-step reasoning process: The items he returned were valued at $700 + $500 = $1200. So far he is out 3000 - 1200 = 1800 after recouping 1200. An item that is 20% more expensive cost 1 + .2 = 1.2 times as much as the item. So that means the bike he sold cost $500 * 1.2 = $600. He sold it for $600 * .8 = $480. From the bike that he had bought for 600, he was out 600 - 480 = 120. So far he is out 1800 + 120 = 1920. If he also bought a toaster worth 100, he was out 1920 + 100 = 2020.
