You built a rectangular deck 14 ft long and 12 ft wide with a set of steps 48 inches wide. You builta railing on the outside using 2X4s around the top, capped with a 6-in deck board. The spindles were spaced on 4-inch or less centers. You built a rectangular patio 14 feet by 16 feet, using 4 inches of concrete for the floor. For the patio you removed 7 inches of dirt and replaced it with 3 inches of sand. To prevent erosion you constructed a 400-square-foot retaining wall. You used stones 15 inches wide, 6 inches high, and 10 inches deep. You are also a groundskeeper for an 18-hole golf course. The greens average 92 feet in diameter on which you applied 5 pounds per 1,000 square feet of 18-5-12 units of fertilizer. The fertilizer comes in 50-pound bags at $32.98 per bag.
