Question

At a restaurant, the bill comes to $40. You decide to leave a 15% tip. How much did you leave for the tip?

Answer 1

The tip of 15% is 15% of the total value of the bill, which is $40. So, we need to take 15% of 40.

Taking 15% of 40 is the same as multiplying 15% by 40. 15% can also be written as:

`15\%=(15\%)/(100\%)=0.15`

So, we can take 15% of 40 by multiplying 0.15 by 40:

`0.15\cdot40=6`

So, the amount left for the tip is $6.
