A school marching band director is using a coordinate plane to determine the formation of 8 band members for the next performance. The origin of the coordinate plane indicates the center of the field, and he uses a point to represent each member. The graph shows the locations of points A, B, and C. • Point D is located at (b, –4). • Point E is located at (0, –a) and is 15 units from point A. • Point F is located in Quadrant III, and the distance between points D and F is 10, which is twice the distance from point F to the y-axis. • Point G lies on the x-axis, and is 4 units above point F.

Aschool typically sells 500 yearbooks each year for 50 dollars each. the economic calls does a project and discovers that they can sell 100 more yearbooks for every $5 decrease in price. the revenue for yearbook sales is equal to the number of yearbooks sold times the price of the yearbook. let x represent the number of $5 decrease in price. if the expression that represents the revenue is written in the form r(x)=(500+ax)(50-bx). to maximize profit, what price should the school charge for the yearbooks? what is the possible maximum revenue? if the school attains the maximum revenue, how many yearbooks will they sell?
