Answers and Step-by-step explanations:
We know that 15% of the meal was $6.60, so we can write this as:
15% * m = 6.60, where m is the cost of the meal before the tip
0.15 * m = 6.60
m = 44
So, the cost of the meal before the tip was $44.
The total cost of the meal and the tip will just be the sum of the value of m and the value of the tip: 44 + 6.6 = $50.60.
Hope this helps!
