Answer:
Radar's additional income for accepting the order is calculated as follows:
Sales - 320 x $460 = $147,200
less Cost of Sales = 320 x $180 + $48,000 = $105,600
Additional Income = $41,600
Explanation:
The additional income of $41,600 is $147,200 - $105,600, which is the result of deducting cost of sales from Sales.
The cost of sales includes the variable cost per bike, including the incremental fixed costs ($48,000) to make this order.
To make a decision whether to accept an order or not, the company needs to consider all variable costs, including the incremental fixed costs. The resulting additional income is what is available to offset the fixed costs.
