Question

Here is my question please answer and give a good explanation: Which expression cannot be used to calculate the total amount paid for a meal (m) including a 15% tip?
A. m+0.15m
B. m+1.15m
C. m+3/20m
D. 1.15m

Answer 1

I'm pretty sure the answer is D. because I don't think anyone would want to take their total meal cost and then multiply it by their tip to make it even larger. You would just add the tip to the meal cost.
