A group of friends went to lunch. The bill was $37.50. A sales tax of 8% was added and then the group tipped 18% on the amount after the sales tax was added. What was the total amount the group paid? help...quick!!

Sagot :

First, there was $37.50.
Then, there was a tax of 8%.
Then, there was a tip of 18%.
Since the tip is after the tax, it's not going to affect it, and we can essentially ignore it.

The real question here is just what is 8% of $37.50?

To find the percent of something, first you need to put the percent as a decimal.

8% in decimal form is 0.08 (If you think about it literally, they're both 8 hundredths)

Finally, just multiply the percent in decimal form by the number.

37.50 dollars × 0.08 = 3 dollars.
