Answer :
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 =[tex]0.09x+0.06x=0.15x[/tex]
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 :-
[tex]\dfrac{0.44x}{0.15x}=2.93333333333\approx3[/tex]
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.
