Answer:

(a). 32 copies

(b). $3060

Step-by-step explanation:

Solution for (a):

P = 60c + 1800

If P is $3720 then;

3720 = 60c + 1800

60c = 3720 - 1800 = 1920

c = $\frac{1920}{60}$ = 32 copies

Solution for (b):

P = 60c + 1800

If c is 21 then;

P = $60(21) + $1800

P = $1260 + $1800

P = $3060
