[Question]Myrtle’s 3 hens lay 3 eggs a day. She would be gone for 7 days and told her neighbor to take as many as they would like. The neighbor took 12 eggs. Once home, Myrtle collected the remaining eggs, dropping 5 on the way into her house. How many eggs does Myrtle have?
[Answer]She has 3 hens that lay 3 eggs a day so they lay 3 * 3 = 9 eggs a day. The hens lay 9 eggs a day and she wasn't able to collect them for 7 days so that means there are 9 * 7 = 63 eggs. Her neighbor took 12 off the 63 eggs so that leaves 63 - 12 = 51 eggs. Myrtle dropped 5 of the remaining 51 eggs so she has 51 - 5 = 46 eggs. The answer is 46.

Question: Lyra bought a pair of shoes at a 20% discount. If she paid $480, how much was the original price of the pair of shoes?
Answer:
Lyra only paid $480 for the pair of shoes which is only 100% - 20% = 80% of the original price. So let x be the original price. Then 0.8x = $480. Thus x = $480 / 0.8 = $600. The answer is 600.
