If you have 80 employees and you grew 116%, what was the amount of original employees?

Nezavi [6.7K]

Answer: 69

Step-by-step explanation:

Let the original employee be x , this means that

116% of x = 80

$\frac{116x}{100}$ = 80

116x = 8000

divide through by 116

x = 8000/116

x = 68.96551724

Since we are dealing with employees , therefore x ≈ 69

This means that there were 69 employees originally
