Question: Out of the 400 emails that Antonia received in her mail, 1/4 were spam emails, while 2/5 of the remaining emails were promotional messages. If the rest of the emails were important emails, calculate the total number of important emails in her inbox.
Answer: Out of the 400 emails, 1 / 4 * 400 = 100 emails were spam emails. The number of emails that were not spam emails is 400 - 100 = 300. 2 / 5 of the emails which were not spam were promotional emails, a total of 2 / 5 * 300 = 120 emails. If the rest of the emails were important emails, there were 300 - 120 = 180 important emails. The answer is 180.
[Question]A van is delivering 180 bottles of drinks to a neighborhood, and each bottle contains either cider or beer or a mixture of two. Out of the 180 bottles, 40 contain only cider, 80 contain only beer, and the rest are a mixture of the two drinks. If the delivery man gives half the number of each bottle of drink to the first house, how many bottles does the first house get?
[Answer]The total number of bottles containing cider or beer is 40 + 80 = 120. If the number of bottles in the van was 180, then 180 - 120 = 60 contains a mixture of the two drinks. At the first house, the delivery man dropped 1 / 2 * 40 = 20 bottles. There were also 1 / 2 * 80 = 40 bottles of beer that the delivery man gave to the first house. Together, the first house received 40 + 20 = 60 bottles of cider and beer. The total number of bottles that had a mixture of the two drinks that were dropped at the first house is 1 / 2 * 60 = 30. The first house got 60 + 30 = 90 bottles of all types of drinks. The answer is 90.
Q: Kelly has 8 chickens that lay 3 eggs each per day. If Kelly sells these eggs for $5 a dozen. How much money will she make in 4 weeks if she sells all her eggs?
A: Each chicken lays 7 * 3 = 21 eggs a week. Each week all the chickens lay 21 * 8 = 168 eggs. In 4 weeks all the chickens lay 168 * 4 = 672 eggs. 672 eggs equal 672 / 12 = 56 dozens. Kelly would make 56 * 5 = 280 dollars. The answer is 280.
Question: Alfred likes to save $1,000.00 over 12 months for his Christmas shopping. He has $100.00 left over from last year's holiday to put towards this year's goal. How much money does Alfred now need to save each month in order to reach his goal in 12 months?
Answer: He wants to save $1,000.00 and he has $100.00 left over so he still needs to save 1000 - 100 = $900.00. He wants to save $900.00 over 12 months so that means he needs to save 900 / 12 = $75.00 per month. The answer is 75.

[Question]Stefan goes to a restaurant to eat dinner with his family. They order an appetizer that costs $10 and 4 entrees that are $20 each. If they tip 20% of the total for the waiter, what is the total amount of money that they spend at the restaurant?
[Answer]
The total cost of the entrees is 4 * $20 = $80. The total cost of the dinner is $80 + $10 = $90. The tip is $90 * 0.20 = $18. The total cost with tip is $90 + $18 = $108. The answer is 108.
