Question

The production cost, represented by y, of smart phone devices are equal to the product of computing components (a) and the square of the number of devices (x), added to the product of labour (b) and number of devices (x); after which savings on reusable material (c) are subtracted. Write down an equation to represent the production cost y) in terms of ax. b and c​

Answer 1

y = ax^2 + bx - c

Explanation:

The product means multiply

The production cost(y) = computing components (a) * number of devices (x) + product of labour (b) * number of devices (x) - savings on reusable material (c)

Therefore,

y = ax^2 + bx - c
