From the graph, estimate the average rate of change in the cost for production levels between 600 and 900 printers. 3.

Answer 1

Multiple Questions , hence only First Question Answered (Case Study-3)

Ans-1

Average rate of change of cost of production = change in cost / change in prduction levels

Cost at 300 levels = 55000 as read from the graph

Cost at 600 level = 80000

Applying the formula we get = (80000 - 55000) / (600 - 300) = 25000/300 = 83.33

Ans-2

Cost at 600 levels = 80000 as read from the graph

Cost at 900 level = 92000 as read from the graph

Applying the formula we get = (92000 - 80000) / (900 - 600) = 12000/300 = 40

Ans-3

The production process is becoming efficient with high production levels.This is very evident from the above two readings of average rate of change in cost where rate of change is almost halved from 83 to 40 .

Ans-4

Change in temprature / change in time = (76 - 58) / (11 - 8) = 18 / 3 = 6

Ans-5

Change in temprature / change in time = (69 - 80)/(5-1) = -11/4 = -2.75
