We can solve this problem by using the formula:
1 + fractional increase = (original employees + new employees) / original employees
Lets say,
x = original employees
Therefore substituting the known values:
1 + 0.05 = (x + 30) / x
1.05 x = x + 30
0.05 x = 30
x = 600
Therefore the number of employees working now is:
<span>x + 30</span>
<span>= 630 employees</span>
(1 / 2) x e x meters =
1.35914091 meters
