Answer: c. $2,526,666.
Step-by-step explanation:
When calculating amount of research and development costs charged to Sheridan for 2021, the concern should be for period costs i.e, costs that are incurred for 2021 alone. Therefore the Equipment cost cannot be put here because as an Asset it was purchased for future use and so cannot be just for 2021.
The costs therefore are all of the above EXCEPT cost.
= Materials + Depreciation + Personnel Costs + Consulting fees + Indirect Costs
= 915,000 + 441,666 + 715,000 + 265,000 + 190,000
= $2,526,666
Correct answer is Option C
