Answer: $38,410,000
Explanation:
When recording investments in fixed assets, it is best to use the market value at the time.
The market value of the land will therefore be the relevant cost here.
Initial investment in fixed assets = Market value of land + Cost to build plant + Cost of grading
= 7,700,000 + 29,300,000 + 1,410,000
= $38,410,000
