Question

the total cost of manufacturing 100 cameras per week is 700 $ and 120 cameras per week is 800 $ ,the the cost equation ,assuming it to be linear is

Answer 1

You have two points on the graph of y(x):

(100,700) and (120,800)

The slope is 100/20 = 5

(y-700)/(x-100) = 5

y = 5(x-100) + 700
y = 5x +200

Answer 2

I don`t have any response about that
