Answer:
We are to find the error made by Sadie and then find the correct simplification.
The error Sadie made is that she wrote
as
instead of
.
The square root of
is
and so she could have further simplified.
The correct simplification is shown below:

20 + 40x = 260
40x = 260 - 20
40x = 240
x = 240/40
x = 6 fulltime employees needed
