Question

A waitress works 1.75 hours less in the afternoon than in the evening. If she works 5  

Answer 1

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.

Answer 2

Answer:

She worked $6\frac{7}{8}$  hours in evening.

Step-by-step explanation:

Suppose, x be the hours waitress worked in evening,

Given,

She works 1.75 hours less in the afternoon than in the evening.

Thus, the number of hours she worked in afternoon = x - 1.75,

According to the question,

$x-1.75 = 5\frac{1}{8}$

$x-\frac{175}{100}=\frac{41}{8}$

$x-\frac{7}{4}=\frac{41}{8}$

$x=\frac{41}{8}+\frac{7}{4}$

$x=\frac{41+14}{8}$

$x=\frac{55}{8}=6\frac{7}{8}$

Therefore, she worked $6\frac{7}{8}$ hours in evening.
