a. n = 500 and C = 10
Substitute values into the equation and solve for k.
10 = k + 2000/500
10 = k + 4
6 = k
b. n = 250 and k = 6
Substitute values into the equation and solve for C.
C = 6 + 2000/250
C = 6 + 8
C = 14
c. C = 8.5 and k = 6
Substitute values into the equation and solve for n.
8.5 = 6 + 2000/n
2.5 = 2000/n
n = 2000/2.5
n = 800
