Answer:

50

Step-by-step explanation:

In the expression [tex]n=10p+20,[/tex] p represents the yearly gross profit in millions of dollars and n represents the total number of employees.

When the yearly gross profit was 20 million dollars, then the number of employees was

[tex]n=10\cdot 20+20=200+20=220.[/tex]

When the yearly gross profit was 15 million dollars, then the number of employees was

[tex]n=10\cdot 15+20=150+20=170.[/tex]

Hence, the decrease in the number of employees is

[tex]220-170=50.[/tex]
