[Question]: Lyle wants to buy himself and his friends a sandwich and a pack of juice. A sandwich costs $0.30 while a pack of juice costs $0.2. If Lyle has $2.50, how many of his friends can have a sandwich and a pack of juice?
[Answer]: A sandwich and a pack of juice cost $0.3 + $0.2 = $0.50. With Lyle's $2.50, he can buy $2.50 / $0.50 = 5 sets of sandwiches and juice. Therefore, 5 - 1 = 4 of his friends can have a sandwich and a pack of juice since the other 1 set is for Lyle himself.
So the answer is 4.

[Question]: Meadow has a business that sells baby diapers to her local townspeople. She orders 30 boxes of diapers containing 40 packs weekly, with each pack having 160 diapers. She sells each diaper for $5. How much money is Meadow making from selling all her diapers?
[Answer]: When she orders 30 boxes, the total number of packs in the boxes is 30 * 40 = 1200 packs. If a pack has 160 diapers, 1200 packs contain 1200 * 160 = 192000 diapers. After selling all the diapers, Meadow gets 192000 * $5 = $960000.
So the answer is 960000.

[Question]: Mike is saving up to buy a house. He puts away 10% of his $150,000 a year salary. He needs to save up 20% of the cost of a $450,000 house for a downpayment. How long will it take?
[Answer]:
He saves 150,000 * .1 = $15,000 per year. He needs 450,000 * .2 = $90,000. So he needs to save for 90,000 / 15,000 = 6 years.
So the answer is 6.
