Let the constants be K and M
C = K + Md
30 000 = K + 400 M .....(i)
42 000 = K + 600 M .....(ii)
30 000 = K + 400 M
12 000 = 200 M
60 = M
30 000 = K + 400 x 60
K = 30 000 - 24 000 = 6 000
C = 6 000 + 60M
= 6 000 + 60M
= 6 000 + 60(800)
= 6 000 + 48 000
=sh 54 000

A factory assembles computers and normally produces 600 in x days.
i) Write down an expression involving x for the number produced per day
ii) The rate of production is increased so that 600 are now produced in one day less (x -1). Write down an expression involving x for the number produced
iii) If the difference between these daily rates of production is 50, form an equation in x and show that it reduces to x2 - x - 12 = 0
iv) Hence find the number produced per day
