Question

a family went out to dinner and the cost of the food was $80 .If the trip given was 15%, what was the total cost

Answer 1

12 dollars.

80/10=8
8/2=4
8+4=12

Answer 2

Hi! :)

So i assume you meant the tip, not trip, but that's fine.

An easy way to calculate the tip is to move the decimal on the percentage left two spaces, then multiply the decimal by the food cost.

For example, in this case you would make the 15% into .15 and multiply .15 by 80.

.15*80=12.

This means you would leave a $12 tip, and to get your total bill just add the tip to the food cost.

12+80=92

So your total would be $92

Hope this helps!
