Answer:
$90,000
Step-by-step explanation:
We could allocate assembly overhead on the basis of the parts used in the assembly process:
wheels ⇒ 300,000 x 2 parts = 600,000 parts
seats ⇒ 600,000 x 3 parts = 1,800,000 parts
total parts assembled 2,400,000 parts
overhead costs per part assembled = $360,000 / 2,400,000 parts = $0.15 per part
so the overhead allocated to wheels should be = 600,000 parts x $0.15 per part = $90,000
