Sam wishes to enclose an 800 ft2 rectangular community garden. She’ll enclose three of the
sides with wooden fence that costs $4.20/foot to install. The fourth side is visible from the
road, so on that side she’ll build a decorative stone wall that costs $6.00/foot to install. Use
calculus to determine the minimum possible cost to enclose the garden according to Sam’s
specifications. (10 p

The graph below shows the price of different numbers of mats at a store: a graph is shown. the values on the x axis are 0, 2, 4, 6, 8, 10. the values on the y axis are 0, 21, 42, 63, 84, and 105. points are shown on ordered pairs 0, 0 and 2, 21 and 4, 42 and 6, 63 and 8, 84. these points are connected by a line. the label on the x axis is number of mats. the title on the y axis is price in dollars. which equation can be used to determine p, the cost of b mats?
