Question

Capri went to eat at the Wheelhouse yesterday. The meal cost $18.60. She wants to leave a 15% tip. How much will the meal cost with tip included? (Please show work)

Answer 1

18.60 x .15 = 2.79
18.60 + 2.79= 21.39

Answer 2

For your calculation, have your original cost times by the amount you want it raised by. In this case, it is raised by 15%, including the $18.60, so it is:
18.60*1.15=$21.39
