[Question]: Oliver has $40 and 200 quarters. If he gives his sister $5 and 120 quarters, how much money in total is he left with?
[Answer]: The 200 quarters equals 200 * $0.25 = $50. Oliver has a total of $40 + $50 = $90. He gives his sister 120 * $0.25 = $30 in total from the quarters. The total amount he gave to his sister is $30 + $5 = $35. Oliver is left with $90 - $35 = $55.
So the answer is 55.

[Question]: Jackson is making pancakes with three ingredients: flour, milk and eggs. 20% of the bottles of milk are spoiled and the rest are fresh. 60% of the eggs are rotten. 1/4 of the cannisters of flour have weevils in them. If Jackson picks a bottle of milk, an egg and a canister of flour at random, what are the odds all three ingredients will be good?
[Answer]: First find the percentage of milk bottles that are fresh: 100% - 20% = 80%. Then find the percentage of the eggs that aren't rotten: 100% - 60% = 40%. Then find the fraction of the flour canisters that don't have weevils: 1 - 1 / 4 = 3 / 4. Divide the numerator of this fraction by the denominator and multiply by 100% to convert from a fraction to a percent: 3 / 4 * 100% = 75%. Then multiply the probability that each ingredient is good to find the probability they all are: 75% * 80% * 40% = 24%.
So the answer is 24.

He drives 30 minutes to work and 30 minutes home every day for a total of 30 + 30 = 60 minutes. He makes this drive 5 days a week for a total of 5 * 60 = 300 minutes. There are 60 minutes in 1 hour and he drives 300 minutes, 5 days a week so that's 300 / 60 = 5 hours. He drives 2 hours on both Saturday and Sunday so he drives 2 * 2 = 4 hours on the weekends. He commutes 5 hours during the week and spends 4 hours driving on the weekend for a total of 5 + 4 = 9 hours.
So the answer is 9.
