Pedal Bikes sells unassembled bicycles. Recently, the firm contemplated switching to production of fully assembled bikes, but it determined the net income per unit for the assembled bikes would be $25 lower than that for the unassembled bikes. Shortly after reaching this conclusion, Pedal discovered that it had underestimated its fixed production costs for the unassembled bikes by $20 and overestimated its variable production costs to assemble the bikes by $10. Given these corrected estimates,

• A:it cannot be determined which type of bike Pedal should sell.
• B:Pedal should switch to selling assembled bikes.
• C:it makes no difference which type of bike Pedal chooses to sell.
• D:Pedal should continue selling unassembled bikes.
