We have a question: Gerald thought it would be funny to trick his coworker, who's allergic to peanuts, into eating a peanut butter cookie. When his coworker goes into anaphylactic shock and is taken to the hospital, Gerald is arrested. The judge sentences Gerald to 3 months for assault and 2 years for poisoning, then extends his sentence by 1/3 since this is Gerald's third offense. How many months does Gerald spend in jail?
And an answer: 36
So how you got the answer?
First convert the 2 - year sentence to months: 2 years * 12 months / year = 24 months. Then add the 3 months for assault: 24 months + 3 months = 27 months. Then find how long the 1 / 3 extension is: 27 months / 3 = 9 months. Finally, add up the three lengths of time to find the total sentence length: 27 months + 9 months = 36 months.

We have a question: Mac loves the shape of quarters and is willing to trade money for them, even if he loses value. He tells his brother that he will trade him 3 dimes for a quarter or 7 nickels. He trades for 20 quarters with dimes and 20 quarters with nickels. How many dollars did Mac lose?
And an answer: 3
So how you got the answer?
Three dimes is equal to $.3 because 3 x .1 = .3. Seven nickels is equal to $.35 because 7 x .05 = .35. Each time he trades with dimes he lose $.05 because .3 - .25 = .05. Each time he traded with nickels he lost $.1 because .35 - .25 = .1. He lost $1 from trading with dimes because 20 x .05 = 1. He lost $2 from trading with nickels because 20 x .1 = 2. He lost $3 total because 1 + 2 = 3.

We have a question: James buys 200 lotto tickets for 2 dollars each. Of those tickets 20% are winners. 80% of the winners are for 5 dollars. 1 ticket is the grand prize of $5,000. The other tickets win an average of $10. How much did he profit?
And an answer: 4830
So how you got the answer?
He spent 200 * 2 = $400. There were 200 * .2 = 40 tickets. Of those 40 * .8 = 32 are 5 dollar winners. So they win 32 * 5 = $160. He has 40 - 32 = 8 other winning tickets. Of those 8 - 1 = 7 wins $10. So they win 10 * 7 = $70. So he won 5000 + 70 + 160 - 400 = $4830.
