Q: Nina makes one-of-a-kind jewelry and sells it at a local boutique. She charges $25.00 for her necklaces, $15.00 for bracelets and $10.00 for a pair of earrings. Over the weekend, she sold 5 necklaces, 10 bracelets, 20 earrings, and received 2 orders for a complete jewelry ensemble that Nina charged $45.00 for. How much money did she make over the weekend?

Question: James replaces the coffee for the household. There are 3 other people in the house and everyone drinks 2 cups of coffee a day. It takes .5 ounces of coffee per cup of coffee. If coffee costs $1.25 an ounce, how much does he spend on coffee a week?
Answer: There are 3 + 1 = 4 people in the house. So they drink 4 * 2 = 8 cups of coffee a day. That means they use 8 * .5 = 4 ounces of coffee a day. So they use 4 * 7 = 28 ounces of coffee a week. So he spends 28 * 1.25 = $35. The answer is 35.

[Question]Elsa gets 500 MB of cell phone data each month. If she spends 300 MB watching Youtube and 2/5 of what's left on Facebook, how many MB of data does she have left?
[Answer]
First subtract the 300 MB Elsa spent on YouTube: 500 MB - 300 MB = 200 MB. Then multiply 200 MB by 2 / 5th to find out how much data Elsa spent on Facebook: 200 MB * 2 / 5 = 80 MB. Finally, subtract the data Elsa spent on Facebook from the 200 MB: 200 MB - 80 MB = 120 MB. The answer is 120.
