The variable costs associated with a certain process are GHS0.65 per item. The fixed costs per day have been calculated as GHS250 with special costs estimated as GHS0.02Q2, where Q is the output level produced ( i, e, the number of items produced ).

a)Derive the average cost of production function

b)Calculate the output level at which average cost is minimised

c)Calculate the average cost of production

d)What limitation is placed on Q?

step-by-step explanation:

a 4/6 = 9/12   not proportional

step-by-step explanation:

to find which are not proportional, we can use cross products

if it is true, they are proportional.   if it is not true, they are not proportional.

a 4/6 = 9/12

4* 12 = 6*9

48 = 54

not this is not proportional  

b 2/3 = 12/18  

2* 18 = 3 * 12

36 = 36

this is proportional

c 5/4 = 10/8  

5*8 = 4*10

40 = 40

this is proportional

d 7/5 = 35/25

7*25 = 5 * 35

175 = 175

is proportional

2/3
