Answer:
14 more nurses.
Explanation:
So, there are 3 shifts a day that need 7 nurses each.
To find out how many nurses the hospital needs to employ, they would need to multiply the number of shifts by the amount of nurses needed. '
In this situation it would look like this:
3 shifts x 7 nurses = 21 total nurses
The hospital would need to employ 14 more nurses if they don't want the nurses' shifts to overlap.
Hope this helps!!
