Ahmed,
Below is the proposed solution for your reference.
Richardson Motors (Make or Buy)
The "Make or Buy" problem concerns analysis of relevant costs. Hence, irrelevant costs, like fixed overhead, should be ignored.
"Make" option
To produce one unit of T305, Richardson's relevant costs are as follows:
Materials cost ...................................................... $ 2,000
Handling costs (20%) ......................................... 400
Direct labor ......................................................... 16,000
Variable MOH (1/3 X $24,000) ....................... 8,000
Total relevant product cost/unit ................... $ 26,400
Add: Opportunity cost/unit of T305 ............ 10,400 ($104,000 / 10 produced per month)
Total relevant cost (Make option) ........ $ 36,800
"Buy" option
To purchase one unit of T305 from a supplier, the relevant costs are:
Purchase price per unit ................................... $ 30,000
Handling charge (20% of materials cost) .. 6,000 (20% X $30,000)
Total relevant cost (Buy option) ......... $ 36,000
The opportunity cost of choosing to produce instead of buying from outside is:
Make option ................................................................ $36,800
Buy option ................................................................. 36,000
Incremental/Opportunity cost per unit of T305 $ 800
Number of units produced in a month ............... X) 10 units
Opportunity Cost if "Make" option is chosen ... $ 8,000
I hope this helps.

Ahmed,
The cost data seems to have been missed here. Can you please repost and provide the complete data?

Subject: opportunity cost
Richardson Motors uses ten units of Part Number T305 each month in the production of large diesel engines. The cost to manufacture one unit of T305 is presented below.
Material handling, which is not included in manufacturing overhead, represents the direct variable costs of the Receiving Department that are applied to direct materials and purchased components on the basis of their cost. Richardson's annual manufacturing overhead budget is one-third variable and two-thirds fixed. Simpson Castings, one of Richardson's reliable vendors, has offered to supply T305 at a unit price of $30,000.
Assume the rental opportunity does not exist and Richardson Motors could use the idle capacity to manufacture another product that would contribute $104,000 per month. If Richardson chooses to manufacture the ten T305 units in order to maintain quality control, Richardson's opportunity cost is
the answer is 8,000$ ???
