Suppose the production cost is R 293 250, computing components cost is R 1 035, labour cost is R 4 140 and the savings on reusable material is R 1 725, determine the number of devices produced. (6)

x=15

Step-by-step explanation:

Given production cost is R 293 250, computing components cost is R 1 035, labour cost is R 4 140  and the savings on reusable material is R 1 725.

We know that the production cost equals: y=ax^2+bx-c

Therefore

293 250= 1 035x^2 + 4 140x - 1725

294 975= 1 035x^2 + 4 140x

1 035x^2 +4 140x - 294 975= 0

Divide by 1 035

x^2 + 4x- 285= 0

(x+19)(x-15)=0

x= -19, or x= 15

Choose the positive one since number of devices cannot be zero
