Question

the manager of a furniture factory finds that it costs $2200 to manufacture 100 chairs in one day and $5200 to produce 300 chairs in one day.

(a) Assuming that the relationship between cost C and the number of chairs produced x is linear, find an equation that expresses this relationship.

Answer 1

Draw a line with points (2200,100) (5200,300) that will be your equation

Answer 2

Cost=15*chairs +700

Answer 3

So C=15x+700
