Question

Mrs. Flores gave the waiter $45 for her dinner that included a 25% tip. What is the cost of her dinner before tip?

Answer 1

I know the answer is $36. I have no idea how to work the problem to get to that answer.

Answer 2

I got it! 45 / 1.25=$36

Answer 3

Cost of the meal is x

so you pay for the meal which is x
and you pay for the tip which is .25x
so
x + .25x = 45
1.25x = 45
x = 45/1.25
x = 36
