A manufacturing company hired 30 new employees. This hiring increased the company's total workforce by 5%. How many employees now work at this company?

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:

x + 30

= 630 employees
