Your cousin Vinnie owns a painting company with fixed costs of $200 and the following schedule for variable costs: Quantity Variable Cost Average Fixed Cost Average Variable Cost Average Total Cost (Houses Painted per Month) (Dollars) (Dollars) (Dollars) (Dollars) 1 10 2 20 3 40 4 80 5 160 6 320 7 640 The efficient scale is houses.

The efficient scale is _4houses.

Explanation:

given fixed costs as $200

and variable costs as  1 10 2 20 3 40 4 80 5 160 6 320 7 640

Using

Average fixed cost =Fixed Cost/Q

uantity

Average Variable Cost=Variable Cost /Quantity

Average Total cost Cost =Average fixed cost+ Average Variable Cost

Average fixed cost = 200/1, 200/2, 200/3, 200/4, 200/5, 200/6., 200/7

Average Variable Cost= 10/1, 20/2, 40/2, 80/2, 160/2, 320/2, 640/2

Average Total cost Cost= 200+10. 100+10, 66.67 + 13.33,50+20, 40+32,  33.33 +  53.33,  28.57 + 91.43

Efficient scale, in  which Total Average cost is at it lowest is a  is the mark at which a company can achieve the best economies of scale required  to effectively run  its industry at an advantage. The efficient scale of production here  is the lowest point where Vinnie paint company  can produce such that its Total average costs are minimized

Looking above at the completed table, you will notice that the Average total cost at the least and minimum value  is at $70. this shows that the efficient scale is 4 houses.

they work in some type of way
