Answer:
$57.46
Step-by-step explanation:
The computation of depletion per unit is shown below:-
Depletion per unit = (Salvage value ÷ Total units to be recovered) × (Mine cost ÷ Depletion base)
= (9,000 ÷ 59,000) × ($1,009,000 ÷ 9,000)
= 0.5125 × 112.1111
= $57.46
Therefore for computing the depletion per unit base we simply applied the above formula.
