A waitress works 1.75 hours less in the afternoon than in the evening. If she works 5 1/8hours in the afternoon, how many hours does she work in the evening?
Accepted Solution
A:
If the waitress works x hours in the evening, according to the problem, she works x-1.75 hours in the afternoon. We have given that she works 5.125 hours in the afternoon, which is x-1.75=5.125. BY solving this equation, we find unknown x, which is equal to 6.87 hours and it is the answer to the problem.
