Answer:

she must screen at least 5 and hour

Step-by-step explanation:

175/5=35 a day

35/7=5 and hour

The number of slides, on average, the lab technician can screen in one hour is 5 slides.

Given,

A lab technician must screen 175 slides under the microscope each week.

She works 7 hours a day.

She works 5 days a week.

We must find how many slides she screens in one hour.

We have,

A lab technician must screen 175 slides under the microscope each week.

One week = 175 slides.

She works 5 days a week.

One week = 5 days.

She works 7 hours a day.

1 day = 7 hours.

Multiply 5 on both sides.

5 x 1 day = 5 x 7 hours

5 days = 35 hours.

So,

One week = 5 days

One week = 35 hours

One week = 175 slides

So,

35 hours = 175 slides

Dividing both sides by 35.

35 / 35 hours = 175 / 35 slides

1 hour = 5 slides.

Thus in one hour, the lab technician can screen 5 slides.
