We have the graph for the profit in function of the kilograms of paprika sold.
There is a minimum number of kilograms to be sold for her to make a profit. This minimum value is called break-even point. For the break-even point, by definition, the profit is 0.
In this case, the minimum kilograms of paprika that she has to sell in order to cover her expenses (profit equals 0) is 35 kilograms.
