[Question]It is recommended that men should consume no more than 150 calories of added sugar per day. Mark took a soft drink in the afternoon that contained 2500 calories, 5% of which was from added sugar. Then he bought some bars of candy which had 25 calories of added sugar each. If he eventually exceeded the recommended intake of added sugar by 100%, how many bars of candy did he take?
[Answer]He consumed 2500 calories, 5% of which is added sugar to give 2500 * (5 / 100) = 125 calories of added sugar. He exceeded the recommended intake of 150 calories by 100% for a total consumption of 150 + (150(100 / 100)) = $300. This means he took in 300 - 125 = 175 calories from candy alone. Each candy had 25 calories so 175 calories which means he consumed 175 / 25 = 7 bars?. The answer is 7.
Q: George is about to celebrate his 25th birthday. Since his 15th birthday, he's been given a special $1 bill from his parents. They told him that on his 25th birthday, for every bill he still has, they will give him $1.5 in exchange. He spent 20% of his special bills. How much will he receive from his parents when he exchanges them?
A: He received 10 special bills because 25 - 15 = 10. He has 80% of them left because 100 - 20 = 80. He has 8 left because 10 x .8 = 8. His parents will give her $12 for them because 8 x 1.5 = 12. The answer is 12.

[Question]A parking garage near Nora's house is 4 stories tall. There are 100 spots per level. There are 58 open parking spots on the first level. There are 2 more open parking spots on the second level than on the first level, and there are 5 more open parking spots on the third level than on the second level. There are 31 open parking spots on the fourth level. How many full parking spots are there in all?
[Answer]
There are 4 levels * 100 spots = 400 possible parking spots. The second level has 58 open spots + 2 = 60 open spots. The third level has 60 open spots + 5 = 65 open spots. Total open spots are 58 + 60 + 65 + 31 = 214 open spots. If there are 400 possible spots – 214 open spots = 186 full spots. The answer is 186.
