​(Type a whole​ number.)

To break even, the store needs to cover its monthly operating costs of $2800.

Let's assume the number of bicycles the store needs to sell each month to break even is x.

The store pays an average of $60 per bike, so the cost of x bikes is 60x dollars.

The average selling price of each bicycle is $130, so the revenue from selling x bikes is 130x dollars.

To break even, the store needs the revenue to cover the operating costs: 130x = 2800.

Dividing both sides of the equation by 130, we have:
x = 2800 / 130.

Calculating this value gives us:
x ≈ 21.54.

Since the number of bikes sold must be a whole number, the store must sell at least 22 bicycles each month to break even.
