Q: Steve puts $100 into the bank. Each year he earns 10% interest on the money in the account. How much money will be in the bank after 2 years?
A: At the end of the first year, there will be $100 * (110 / 100) = $110 in the bank account. At the end of the second year, there will be $110 * (110 / 100) = $121. The answer is 121.

Q: A tree on a farm has 10 branches. Each branch has 40 sub-branches with 60 leaves each. If the total number of trees on the farm is 4 and they have the same number of leaves, calculate the total number of leaves on all the trees.
A: If the tree's 10 branches have 40 sub - branches each, the total number of sub - branches on the tree is 10 * 40 = 400. Since each sub - branch has 60 leaves, the tree has 60 * 400 = 24000 leaves. If there are four trees on the farm with the same number of leaves, they all have 24000 * 4 = 96000 leaves. The answer is 96000.

Q: Greg bought a 20-pack of granola bars to eat at lunch for the week. He set aside one for each day of the week, traded three of the remaining bars to his friend Pete for a soda, and gave the rest to his two sisters. How many did each sister get when they split them evenly?
A:
Greg kept 1 granola bar for each of the 7 days of the week, so there were 20 - 7 = 13 bars left. He traded 3 to his friend Pete, so there were 13 - 3 = 10 bars left. His 2 sisters split the rest evenly, so each got 10 / 2 = 5 granola bars. The answer is 5.
