A small business has 15 full-time employees. How many people does the small business employ if the full-time workers make up 30%

Alexxx [7]

Answer:

50 employees

The number of full-time employees = 15

Let the total number of employees = x

$15 = 30 percent of x$

$15 = 30/100 \times x\\x=1500/30 = 50$

The company has a total of 50 employees

(200+x)/6 = 40

200 + x = 240

x = 40
