Tom gave 15% of his savings to charity,35% to his wife and 10% to the butcher to pay last month's bill. after this he had $440 left. how much did he give to his wife?

He gave his wife $385

Step-by-step explanation:

In order to find how much he gave his wife, we first need to determine how much he had to start. We can do this by first finding the percentage that he gave away.

15% + 35% + 10% = 60%

This means that he only has 40% left. Now to find how much he had to start, divide the amount of money he has left ($440) by the percentage that it represents (40%)

440/40% = 1,100

Now that we have the original amount of $1,100, we can multiply it by the percentage he gave his wife (35%) to determine the amount.

1,100 * 35% = 385

the volume is the product of the area of the base, 3x(3x+4), and the height, 3x-1
