Please show work so I can understand better. Thank you!

Part 4 (2 points) Sprinkay has discovered that a small fitting it now manufactures at a cost of $1.00 per unit could be bought elsewhere for $0.82 per unit. Sprinkay has fixed costs of $0.20 per unit that cannot be eliminated by buying this unit. Sprinkay needs 460,000 of these units each year. If Sprinkay decides to buy rather than produce the small fitting, it can devote the machinery and labor to making a timing unit it now buys from another company. Sprinkay uses approximately 500 of these units each year. The cost of the unit is $12.66. To aid in the production of this unit, Sprinkay would need to purchase a new machine at a cost of $2,345, and the cost of producing the units would be $9.90 a unit. Instructions Given the information above: (a) Without considering the possibility of making the timing unit, evaluate whether Sprinkay should buy or continue to make the small fitting. (b) (1) What is Sprinkay' opportunity cost if it chooses to buy the small fitting and start manufacturing the timing unit? (2) Would it be wise for Sprinkay to buy the fitting and manufacture the timing unit? Explain
