[Question]: A store gives a 10% discount for the amount of the sell that was over $1000. John buys 7 items that each cost $200. What does his order cost after the discount?
[Answer]: His order came out to 7 * 200 = $1400. So there was 1400 - 1000 = $400 that qualified for the discount. So his discount saved 400 * .1 = $40. So his purchase came out to 1400 - 40 = $1360.
So the answer is 1360.

[Question]: Thomas is making hummus. One of the ingredients in a hummus recipe is chickpeas. For one serving of hummus, the recipe calls for 1 cup of chickpeas. In a can of chickpeas, there are 16 ounces of chickpeas. In one cup of chickpeas, there are 6 ounces. To make 20 servings, how many cans of chickpeas should Thomas buy?
[Answer]: For 20 servings, Thomas needs 20 * 1 = 20 cups of chickpeas. To have 20 cups, Thomas needs 20 * 6 = 120 ounces. 120 ounces / 16 ounces = 7.5 cans of chickpeas. Since Thomas cannot buy half a can, he needs to buy 8 cans.
So the answer is 8.

[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.
So the answer is 120.
