If the nurse spends 16 hours per week dispensing medicine, and this equates to 40% of her total work time, that would be an that 16 is 40% of the total hours the nurse works. This number must be greater than 16 hours, as that is less than 100% of the total time worked, thus the answer of 14 hrs is not correct.
The correct answer would be 40 (forty) hours worked per week total. Using the formula (hrs worked)/(percent/100). (16)/(40/100) = 40.
