To solve this problem, let's set up an equation, letting n represent the number that you are trying to find.
n/2 - 4 = 2
To begin simplifying this equation, you must add four to both sides.
n/2 = 6
Finally, we must multiply both sides by two, in order to get rid of the denominator of the variable n.
n = 12
We know that this answer is correct because if we plug the value 12 back into the beginning equation for the variable n, it results in a true statement.
Thus, the number is 12.

The net profit per bike is 150-40= 120. Hence to break even, the store needs to profit more than the operating cost of the store. 3840/ 120= 32. The store needs to sell 32 bicycles each month to break even.
