[Question]Josh has $300 in his wallet, and $2000 invested in a business. If the business's stock price rises 30% and then he sells all of his stocks, how much money will he have in his wallet?
[Answer]If the business's stock price rises 30%, then his share on the company is worth 30% multiplied by $2000 plus $2000 that he already had. That results in 30% * $2000 + $2000 = $600 + $2000 = $2600. Since he already had $300, with $2600 more he will have $300 + $2600 = $2900. The answer is 2900.
Q: Annie was given a pack of crayons. The pack contained 21 crayons. She already had a box of 36 crayons in her locker. Her friend Bobby gave her half the amount she already had in her locker.

A: Annie starts with 21 + 36 = 57 crayons. Bobby ends up giving her 36 / 2 = 18 crayons. Annie now has a total of 57 + 18 = 75 crayons. She ends up giving Mary a total of 75 * (1 / 3) = 25 crayons. The answer is 25.
