Use linear, quadratic, and rational equations to solve real-life problems. Solve the following problems 2 1) A picture frame has a total perimeter of 3 meters. The height of the frame is 3 times its width. a) Draw a diagram that represents the problem. Identify the width as 𝑤 and the height as ℎ. b) Write h in terms of 𝑤 and write an equation for the perimeter in terms of 𝑤. c) Find the dimension of the picture frame. 2) The total cost for printing small booklets is $500 (the fixed cost) plus $2 for each booklet printed. a) Express the total cost, 𝐶(𝑥) of producing booklets as a function of the number of booklets, 𝑥. b) Complete the following table 𝐶(𝑥) 𝑥 Number of booklets In dollars 0 50 100 150 200 c) Create a graph of 𝐶(𝑥) on the Cartesian Coordinate d) If the total cost of producing booklets is $1,600, how many booklets were produced? 3) A rectangular play yard is to be enclosed with a fence on three of its sides and a brick wall on the fourth side. If 120 feet of fencing material is available, what dimensions will yield the maximum area?
