Answer:
$16,500
Step-by-step explanation:
When more than one asset is purchased for a lump sum, the basis of each is computed by apportioning the total cost based on the relative FMV of each asset. Lot #3 has a FMV that is 16.5% of the FMV of all of the lots purchased [$20,625 ÷ ($25,000 + $31,250 + $20,625 + $48,125)]. Thus, the basis of Lot #3 is $16,500 ($100,000 × 16.5%).
