In these problems you are asked to find a function that models a real-life situation and use the model to answer question about the situation. Use the guidelines on page 273 to help you. Fencing a Garden plot A property owner wants to fence a garden plot adjacent to a road. As shown in the figure. The fencing next to the road must be studier and costs $5 per foot, but the other fencing costs just $3 per foot. The garden is to have an area of 1200 ft 2 . (a) Find a function that models the cost of fencing the garden. (b) Find the garden dimensions that minimize the cost of fencing. (c) If the owner has at most $600 to spend of fencing, find the range of length he can fence along the road.
