Answer:
The special order should be rejected since it decreases net profit.  
Explanation:
Alpha = $225
Beta = $175
total production capacity = 130,000 pounds
raw materials = $6 per pound
Production costs per unit                        Alpha                Beta
direct materials                                          $42                   $24
direct labor                                                 $42                   $32
variable manufacturing overhead            $26                   $24  
fixed manufacturing overhead                 $34                   $37
variable selling expenses                         $31                    $27
<u>common fixed expenses                          $34                   $29  </u>
total cost per unit                                    $209                 $173
Cane expects to sell 114,000 Alphas. 
Net profit = (114,000 x $225) - (114,000 x $209) = $25,650,000 - $23,826,000 = $1,824,000
If the new sales order is accepted, Cane's revenue will increase to:
- 101,000 x $225 = $22,725,000
- 29,000 x $156 = $4,524,000
- total = $27,249,000
Their total cost will by:
- 114,000* x $209 = $23,826,000
- 16,000 x ($209 - $34 avoidable fixed costs) = $2,800,000
- total = $26,626,000
*This sale increases the output, but previous costs cannot be avoided. 
Net profit with special order = $27,249,000 - $26,626,000 = $623,000
The special order should be rejected since it decreases net profit.
