Question 1100025: If f(x)=5x−100 represents the profit function for x items that require a total of $100 investments and return a profit of $5 each, how many items must be sold to break even? Answer by richwmiller(17219) (Show Source):
You can put this solution on YOUR website! profit=revenue-cost
We know the total investment 100
We know profit per item 5
We don't know revenue.
If the $5 were revenue, then we would need to sell 20 items to break even. There would be no profit.
But there is profit on each item.
The problem is poorly written.
