Question

maximize his revenue. He comes up with the equation y = -0.1x to the second power + 26x, where x represents the selling price and y
represents the revenue earned. In terms of the context, describe in 2sentences at what sale price his book would return maximum revenue and what that revenue would be.

Answer 1

To maximize his revenue, Damar should sell his book at a price of $130, which is calculated from the vertex of the revenue equation \(y = -0.1x^2 + 26x\). At this sale price, he would achieve a maximum revenue of $1,690.
