Q: Apple sold 100 iPhones at their New York store today for an average cost of $1000. They also sold 20 iPads for an average cost of $900 and 80 Apple TVs for an average cost of $200. What was the average cost across all products sold today?
A: The sales for iPhones were 100 iPhones * $1000 per iPhone on average = $100,000. The sales for iPads today were 20 iPads * $900 per iPad = $18,000. The sales for Apple TV’s today were 80 * $200 = $16,000. The total sales for Apple at their New York store today was $100,000 + $18,000 + $16,000 = $134,000. The total number of products sold was 100 + 20 + 80 = 200. The average cost per product sold was $134,000 total sales / 200 total products = $670. The answer is 670.

[Question]Five months ago, Mike earned 10 times more money than Fred. If his salary has increased by 40 percent now, and Fred's salary then was $1000, calculate Mike's salary now.
[Answer]Five months ago, Mike earned ten times more money than Fred, and since Fred earned $1000, Mike earned 10 * 1000 = $10000 more than Fred. The total amount of money that Mike earned five months ago is $10000 + $1000 = $11000. Mikes salary has increased by 40 / 100 * $11000 = $4400. Mike's current salary is $11000 + $4400 = $15400. The answer is 15400.
