The marginal cost function of producing q mountain bikes is 600/0.3q+5.

If the fixed cost in producing the bicycles is 2200, find the total cost to produce 30 bicycles.

If the bikes are sold for 205 each, what is the profit (or loss) on the first 30 bicycles?

Find the marginal profit on the 31st bicycle ...?

MArginal cost is the adjustment in all out cost that emerges when the amount created changes by one unit. (In another word subordinate of cost wrt unit)

So we coordinate to get Cost work

∫30 600/0.3q+5 (dq) 0

we get 9798.66 from joining.

We add that to settle cost 2059.23+2200=4259.24

So 4259.24 is the cost.

Income from offering the bicycle is 205*30=6150

and Profit=Revenue-Cost

6150 - 4259.24=1890.76

Presently Marginal Profit

MArginal benefit is the term used to allude to the contrast between the minor cost the peripheral income for delivering one extra unit of creation.

Marginal Profit=Marginal Revenue-Marginal Cost

Marginal Cost=600/0.3q+5.

We should connect to 31 to get 41.958

Revenue = 205q

Marginal rev=205

Marginal Profit = 205-41.958=163.042
