The lunch bill for marty and breanna at a diner totaled $18.37. Tax on the meal was 6%, and they wanted to leave a 15% tip. How much was the meal including tax and tip?

Step-by-step explanation:

The lunch bill for marty and breanna at a dinner totaled $18.37. Tax on the meal was 6%. The amount of tax on the meal would be

6/100 * 18.37 = 0.06 * 18.37 = $1.1022

Cost of the meal including the tax would be

18.37 + 1.1022 = $19.4722

They wanted to leave a 15% tip. The amount of the tip would be

15/100 * 18.37 = 0.15 * 18.37 = $2.7555

Therefore, the total cost of the meal, including tax and tip would be

19.4722 + 2.7555 = $22.23
