Answer:
2.07 or 13.57
Step-by-step explanation:
First, you'd want to calculate the total bill. So you'd do the original bill multiplied by 1.18 (signaling the addition of the tip).
46 · 1.18 = 54.28
If you're calculating only the tip, it would be 46 · 0.18= 8.28
Then, since there is Martha, and 3 of her friends, you'd divide the bill (54.28) by 4 people. However, since the question is a little unclear on whether it is asking how much each person should leave for the tip, or leave overall, there are 2 possible answers.
Overall, each person would leave 54.28/4 = 13.57.
For the tip only, each person would leave 2.07.
