Question: David has a store where he sells cell phones. When he takes inventory at the end of the day, he notices that he has 10 Samsung cell phones but he started the day with 14 Samsung cell phones. Then he notices that he has 5 iPhones and in the initial inventory, but started with 8. His staff then told him that in the afternoon they realized that 2 Samsung cell phones were damaged and 1 iPhone had a manufacturing defect in the screen, so they threw these out during the day. What was the total number of cell phones that were sold today?
Answer: The actual initial inventory of Samsung cell phones was 14, but there were 2 defective phones so 14 - 2 = 12 is the initial inventory of working Samsung phones. The actual initial inventory of iPhone cell phones was 8, but there was one defective phone, so 8 - 1 = 7 is the actual initial inventory of working iPhones. Thus only 12 - 10 = 2 Samsung cell phones were sold. Thus only 7 - 5 = 2 iPhones were sold. Thus the total number of phones sold is 2 Samsung + 2 iPhone = 4 cell phones. The answer is 4.
[Question]The sum of the ages of three boys is 29. If two of the boys are the same age and the third boy is 11 years old, how old are the other two boys?
[Answer]The third boy is 11 so the sum of the ages of the first two is 29 - 11 = 18. The ages of the first two boys are equal so each of them is 18 / 2 = 9 years. The answer is 9.

Question: Jim's bi-weekly gross pay is $1120. He automatically has 25% of his paycheck go into his retirement account. They also take $100.00 out of each paycheck for taxes. After money is taken out for retirement and taxes, how much money will be on Jim's paycheck?
Answer: He has 25% of his take - home pay automatically enrolled into his 401k so that's .25 * 1120 = $280.00. His take - home pay is $1120.00 and $280.00 is taken out for retirement so that leaves 1120 - 280 = $840.00. They also take $100.00 out of his paycheck for taxes so his paycheck will be issued for 840 - 100 = $740.00. The answer is 740.
