I went to the music shop and there were CDs of The Life Journey for $100, A Day a Life for $50, and When You Rescind for $85 on display. If I bought 3 of each CD to share with my friends, what's the total amount of money I spent in the shop?
Let's think: The total cost of The Life Journey is 3 $100 = $300. The total cost of When You Rescind is 3 $85 = $255. The total cost of A Day a Life is 3 $50 = $150. The total cost for all the CDs is $150 + $255 + $300 = $705.. The answer is: 705.

A fixer uses 30% of the nails in a container to repair the kitchen. He also used 70% of the remaining nails in the container to repair the fence. If there were 400 nails in the container, how many nails are remaining?
Let's think:
The fixer used 30 / 100 * 400 = 120 nails to fix the kitchen. The number of nails remaining in the container after he fixes the kitchen is 400 - 120 = 280. He also uses 70 / 100 * 280 = 196 of the nails remaining in the container to fix the fence. The total number of nails which the fixer hasn't used is 280 - 196 = 84.. The answer is: 84.
