Ladders used by fruit pickers are pically tapered with a wide bottom for stability and a narrow top for ease of picking. If the bottom rung of such a ladder is 49 inches wide and the top rung is 19 inches wide. Stating explicitly the formulae used, determine: (i) How many rungs does the ladder have if each rung is 2.5 inches shorter than the one below it? (ii) How much material would be needed to make the rungs for the ladder described?
