HELP ME please answer this question A bicycle store costs $2400 per month to operate. The store pays an average of $60 per bicyc
tia_tia [17]

Answer:

40  

Step-by-step explanation:

                  Let b = the number of bicycles sold

         Then 120b = monthly income

And 2400 + 60b = monthly expenses

At the break-even point,

120b = 2400 + 60b

60b = 2400

     b = 40

The store must sell 40 bicycles per month to break even.
