Question: Ned opens a left-handed store. He sells left-handed mice. They cost 30% more than normal mice. He sells 25 a day and his store is open every day except Sunday, Thursday, and Friday. If normal mice cost $120 how much money does he make a week?
Answer: The left - hand mice cost 120 * .3 = $36 more than right - handed ones. So they cost 120 + 36 = $156. So he makes 156 * 25 = $3900 a day. The store is open 7 - 3 = 4 days a week. So in a week, he makes 3900 * 4 = $15,600. The answer is 15600.

Q: Paityn has 20 red hats and 24 blue hats. Her friend Zola has 4/5 times as many red hats as she has and twice the number of blue hats. If they combine all the hats together and share them equally between themselves, calculate the number of hats each gets.
A: Paityn has a total of 20 hats + 24 hats = 44 hats. The number of red hats that Zola has is 4 / 5 * 20 hats = 16 hats. Zola also has 2 * 24 hats = 48 blue hats. Zola has a total of 48 hats + 16 hats = 64 hats. When they combine their hats, they have 64 hats + 44 hats = 108 hats. If they share the hats equally, each get 108 hats / 2 people = 54 hats / person. The answer is 54.
