Managerial Accounting... This is the second time I posted this question.

Initially, I got the entire problem wrong and was perplexed as to why. I posted the question to Chegg (with my initial incorrect answer) and the Expert reposted portions of my incorrect answer. Whoever answers this question, can you explain how you came to the answer, please? Thank you.

CHEGG EXPERT ANSWER (Incorrect)

Gilberto Company currently manufactures 66,000 units per year of one of its crucial parts. Variable costs are $2.00 per unit, fixed costs related to making this part are $76,000 per year, and allocated fixed costs are $63,000 per year. Allocated fixed costs are unavoidable whether the company makes or buys the part. Gilberto is considering buying the part from a supplier for a quoted price of $3.30 per unit guaranteed for a three-year period. Calculate the total incremental cost of making 66,000 and buying 66,000 units. Should the company continue to manufacture the part, or should it buy the part from the outside supplier?
