Question

Brian is finishing a meal at his favorite restaurant. The check shows that the cost of the food is $42. He adds a 15% tip to the amount on the check. What is the total amount Brian paid? Write your answer up to two decimal places.

Answer 1

48.30        you move the decimal point back (to the left) to get 10 percent then since 5 is half of 10 to get the rest of the 15 percent you take half of ten percent witch is 5 and add the 10 and 5 percent to get the total 15 percent witch is 6.30 then add 6.30 for a total of what he paid

Answer 2

42 x 0.15= 6.30 for the tip
$42 + 6.30 tip= $48.30
