[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]Dan can get to the center of a lollipop in 58 licks. Micheal does it in 63 licks. Sam & David each take 70 licks to get to the center of a lollipop while Lance only needs 39 licks. What is the average amount of licks it takes to get to the center of a lollipop?
[Answer]Dan takes 58 licks, Michael takes 63, Sam takes 70, David takes 70 and Lance takes 39 for a total of 58 + 63 + 70 + 70 + 39 = 300 licks. There are 5 people and the total amount of licks is 300 so the average is 300 / 5 = 60 licks to get to the center of a lollipop. The answer is 60.

[Question]Henrietta is repainting her house. The walls in the living room take up 600 square feet. She has three bedrooms. The walls in each bedroom take up 400 square feet. If one gallon of paint can cover 600 square feet, how many gallons of paint does Henrietta need to paint her house?
