Final answer:
Given the total weight of Edith and her tools, a ladder with a Type I duty rating (250 pounds) would be ideal. This accounts for her weight and also provides a safety buffer.
Explanation:
Industry standard duty ratings should be considered when deciding the type of ladder Edith should use. The total weight, including Edith's weight and the weight of the tools, is 225 pounds (195 pounds + 30 pounds). Ladders are rated by their safe load capacity. The ANSI (American National Standards Institute) classifies ladders into types: Type III (200 lbs), Type II (225 lbs), Type I (250 lbs), Type IA (300 lbs), and Type IAA (375 lbs).
Given Edith's total weight is 225 pounds, it falls just within the Type II duty rating. However, to have a safety buffer and ensure a safe and secure climbing experience, a ladder with a Type I (250 pounds) rating would be more ideal.
