Question

If you treat 2 friends to lunch, the 1st lunch is $12.35, the 2nd lunch is $14.22, and your lunch is $11.47. You want to add a 20% tip. How much will you pay in total?

Answer 1

Your 2 friends lunch and yours cost = 12.35 + 14.22 + 11.47 = $38.04

20% tip cost = 20/100 of 38.04 = 0.20 x 38.04 = $7.61

Total amount paid = 38.04 + 7.61 = $45.65
