Mr. Geometry, Mr. Algebra and Ms. Calculus ordered similarly priced lunches and agreed to split the bill plus a 15% tip. How much should each person pay if the bill is $24.60?



Answer :

Add 15% to the bill and then divide by 3.

they will pay (115% of $24.60) / 3

= (1.15 x 24.60) / 3

= $28.29 / 3

= $9.43
