Answer: 50 bicycles
Explanation:
The breakeven quantity is the amount that must be sold to bring the profit to zero.
You can use the following formula to calculate it:
= Fixed cost / Contribution margin
Fixed cost= $4,500 per month to operate
Contribution margin = Selling price - Variable cost = 155 - 65 = $90
Breakeven = 4,500 / 90
= 50 bicycles
