The question is
The big brick bakery sells more bagels when it reduces its prices, but then its profit changes. The function $$y=−1000(x−0.55)^2+300$$ models the bakery's profit (in dollars) from selling bagels, where x is the price of a bagel in dollars. The bakery wants to maximize the profit.
The main question is.
1) What price should the bakery charge to maximize its profit from bagels?
For this I don't even know where to start it does not give me any numbers to plug on or anything. How do I find it? How do i start this?
