Come up with a question and reasoning that would justify [750] as the answer.
The question is: A mosquito sucks 20 drops of blood every time it feeds on someone. If there are 5000 drops per liter and you have to lose 3 liters of blood to die, how many mosquitoes would have to feed on you to kill you?
Reasoning: First find the total number of liters a mosquito sucks in one feeding: 20 drops / 5000 drops / liter = .004 L / feeding. Then divide the lethal amount of blood by the amount of blood one mosquito can drain: 3 L / .004 L / feeding = 750 feedings.

Come up with a question and reasoning that would justify [300] as the answer.
The question is: John injures his shoulder while lifting weights. After the injury, his bench press goes down 80%. After a bit of training, he manages to triple the weight he can bench. If he started with a 500-pound bench press, what is it now?
Reasoning: He lost 500 * .8 = 400 pounds from his bench. So his bench went to 500 - 400 = 100 pounds. After training it increased to 100 * 3 = 300 pounds.

Come up with a question and reasoning that would justify [23248] as the answer.
The question is: Ever since she was a little girl, Sheila has dreamed of traveling the world. To help fund her dream, she bought a large piggy bank in December and started saving. By last week, she had saved $3,000. Pleased with her progress, she has decided to continue saving $276 per month, for 4 years. Today, Sheila's family secretly added $7,000 into the piggy bank. At the end of 4 years, how much money will be in Sheila's piggy bank?
Reasoning: Today, Sheila's piggy bank has $3000 + $7000 = $10000. Sheila will be saving for 4 years which is equivalent to 12 months / year * 4 years = 48 months. In 4 years, she will save $276 / month * 48 months = $13248. The piggy bank will have a total of $10,000 + $13,248 = $23248.
