If the cost of installing the lemonade stand is $ 50, Betty must raise a minimum of $ 51 to make a profit. When selling the glasses of lemonade to $ 1, Betty must sell 51 glasses to surpass the $ 50 of cost, and begin to obtain a surplus that forms a profit.

If she only sold 50, she would recover the initial investment but she would not have earnings.

If she sold less than 50, her business would show a negative balance.
