Question: Tim spent $50.00 on Chinese take-out. 80% of the cost went to 4 entrees. The rest of the money went to 2 appetizers that each cost the same amount. How much was the price of a single appetizer?
Answer: He spent $50.00 and 80% of the meal went to entrees so he spent 50 * .80 = $40.00 on entrees. He spent $50.00 and $40.00 went to entrees so that leaves $50 - $40 = $10.00 for appetizers. Each appetizer costs the same amount and he spent $10.00 all together so each appetizer is $10 / 2 = $5.00. The answer is 5.

[Answer]Marie will read 20 but gain 6 unread messages a day, so she will lower the number of messages by 20 - 6 = 14. Thus, it will take her 98 / 14 = 7 days to read all her unread messages. The answer is 7.
Q: There were 600 cookies in a box. Nicole ate 2/5 of the total number of cookies, while Eduardo ate 3/5 of the remaining amount. What percentage of the original cookies remained?
A: Nicole ate 2 / 5 of the total number of cookies, which is 2 / 5 * 600 = 240. The total number of cookies that remained in the box after Nicole ate 240 is 600 - 240 = 360. Eduardo then ate 3 / 5 of the remaining cookies, a total of 3 / 5 * 360 = 216 cookies. The total number of cookies that remained after Eduardo ate 216 is 360 - 216 = 144. The percentage of the cookies that remained out of the original amount is 144 / 600 * 100% = 24%. The answer is 24.
Question: Josh has a device that automatically records the temperature in his lab every 5 seconds. To perform an analysis of environmental conditions, Josh lets the device record data for one hour. How many instances of data will the device record?
Answer: There are 60 minutes in an hour, and 60 seconds in a minute so there are 60 * 60 = 3600 seconds in an hour. The device records data every 5 seconds so there will be 3600 / 5 = 720 instances of data in an hour. The answer is 720.
[Question]James is building an army of Warhammer 40k figurines. It takes him 20 minutes to paint a space marine and 70 minutes to paint a dreadnought. If he paints 6 space marines and 2 dreadnoughts, how long does he spend painting total?
[Answer]First find the total time James spends painting space marines: 20 minutes / marine * 6 marines = 120 minutes. Then find the total time James spends painting dreadnoughts: 70 minutes / dreadnought * 2 dreadnoughts = 140 minutes. Then add the two amounts of time to find the total time James spends painting: 120 minutes + 140 minutes = 260 minutes. The answer is 260.
