Answer: $16,925.90 increase
Step-by-step explanation:
Company already has the excess capacity to handle this order so the fixed costs will not be included as they would have already been incurred.
Cost of manufacturing the trees would be:
= Variable cost + Fixed cost
= ((51.61 + 3.80 + 1.00 + 8.26 for white tree) * 230 trees) + 5,000 for molds
= (64.67 * 230) + 5,000
= $19,874.10
Incremental revenue = 230 trees * 160
= $36,800
Incremental operating income = 36,800 - 19,874.1
= $16,925.90 increase
