The cost C of operating a computer business is partly constant and partly varies as the square of labour input L. If C = 25,000 when L = 20 and C = 45,000 when L = 30. Find C when L = 8.

Answers

C = k + hL²
25,000 = k + 400h
45,000 = k + 900h –
20,000 = 500h
h = 40
25,000 = k + 400 (40)
K = 9,000
C = 9000 + 40L²
C = 9000 + 40(8)²
C = ksh.11,560
