Question

Dinner at a restaurant cost $55.00. The diners decide to leave a 20% tip. What is the cost of their total bill?

Answer 1

Their cost would be $66.00

Explanation:

The way i do it is i take ten percent of the total. Which is 55. 10% of 55 is 5.5. And since the diners decide to leave a 20% you multiply 5.5 by two and get 11. So that is an $11.00 tip they left.

So next you would add the $11.00 tip to the $55.00 and you would get a total cost of $66.00.

The diners total cost after they leave a 20% tip would be $66.00

Answer 2

66

Explanation:

First find the cost of the tip

tip = 55 * 20%

= 55 * .20

= 11

The tip is 11 dollars

Add this to the bill

55+11 = 66

The total bill is 66 dollars
