Answer:  b) 3

Step-by-step explanation:

Let the total hours Janelle spent on all the five tasks be x.

According to the question , we have

Number of hours that Janelle will spend working at the counter is 0.44x

Number of hours that she will spend processing new books is 0.09 x

Number of hours that she will spend repairing bindings = 0.06x

Then , Number of hours that she will spend processing new books and repairing bindings =\(0.09x+0.06x=0.15x\)

The number of times number of hours that Janelle will spend working at the counter is of  the number of hours that she will spend processing new books and repairing bindings is given by :-

\(\dfrac{0.44x}{0.15x}=2.93333333333\approx3\)

Hence, the  number of hours that Janelle will spend working at the counter is about three times the number of hours that she will spend processing new books and repairing bindings.
