Question: On the night of the dance, 400 students show up to the party. 70% of the students who showed up were invited. If 40% of those invited to the party had their invitation revoked and were not allowed into the party, how many invited students attended the party?
Answer: On the night of the dance 70 / 100 * 400 = 280 students who showed up to the party were invited. If 40% of those invited to the party had their invitation revoked, there were 40 / 100 * 280 = 112 students who showed up and had their invitation revoked. The number of invited students who attended the party is 280 - 112 = 168. The answer is 168.

Question: Jacob's water tank can hold up to 50 liters of water. Jacob collects water from the river and rain to fill his water tank. He can collect 800 milliliters of water from the rain and 1700 milliliters of water from the river every day. How many days does Jacob need to fill up his water tank?
Answer: Jacob collects 800 + 1700 = 2500 milliliters of water from the river and rain every day. Since 1 liter is equal to 1000 milliliters, then 50 liters is equal to 50x1000 = 50,000 milliliters of water. Therefore Jacob needs 50,000 / 2500 = 20 days to fill his water tank. The answer is 20.

[Question]Paige bought some new stickers and wanted to share them with 3 of her friends. She decided to share a sheet of 100 space stickers and a sheet of 50 cat stickers equally among her 3 friends. How many stickers will she have left?
[Answer]
Paige has 100 space stickers that she is dividing among 3 friends, so 100 stickers / 3 friends = 33 stickers for each friend, with 1 remaining. She also has 50 cat stickers that she is diving among 3 friends, so 50 stickers / 3 friends = 16 stickers for each friend, with 2 remaining. So Paige will have 1 remaining space sticker + 2 remaining cat stickers = 3 stickers left. The answer is 3.
