Answer 1

Given that the number of employees follows the equation n=10p+20, where p is the yearly gross profit, if the profit declined from 20 million to 15 million, the decrease in the number of employees would be:
Number of employees when p=20
n=10(20)+20
n=200+20
n=220

Number of employees when p=15
n=10(15)+20
n=150+20=170
thus the decrease will be:
220-170=50

Answer: j) 50
