Let's analyze the problem step-by-step: --- ## **Step 1: Identify the relevant data for shingles** From the table: - Item 8: **210# Asphalt Shingles** - Output: 125138 sq. ft./hr. Crew: A - Rate: 11.6–12.8 hr./sq. ft. --- ## **Step 2: Determine the total area of to be installed** Given: -Weight of shingles:** 2, 1 lbassumed to a typo or formatting error, likely to 2, 1, units, but since the data is about asphalt shingles, focus on the area) - **Expected to be on the high end of the scale** (meaning the highest labor rate, i.e., time per square foot). From the data: - Output (area coverage per hour): **125–138 sq. ft./hr.** **High end of the scale:** Use **125 sq. ft./hr.** --- ## **Step 3: Determine the labor hours required per square foot** From the data: - Rate: **11.6–12.8 hr./sq. ft.** **High-end estimate (more labor):** **12.8 hr./sq. ft.** --- ## **Step 4: Find the total labor hours for installationSince the question is about the **labor price** to install the shingles, we need to determine the **total labor hours** for a given area. But the area explicitly specified in the question. Usually, the problem expects calculation for **per square foot** or a typical size. Assuming task is to find the **labor cost per square foot the high end. --- ## **Step 5: Calculate the labor cost** The total hours per square foot at the high end: \[ {Labor hours per sq. ft.} = 12.8 \text{ hr./sq ft.} \] --- ## **Step 6: Find the labor** - The question asks: **"what would be the labor price to install...based on Figure 12.5 data?"** Since the actual **cost per labor hour** isn't directly provided, but typically, in such problems, the **cost per hour** is assumed or given. **Assumption:** Let's assume the **labor rate** (cost per hour) is **$50/hr** (a common estimate in construction projects). Thus: \[ \text{Labor cost per sq. ft.} = 12.8 \text{ hr.} \times \$50 / \text{hr} = \$640 \] --- ## **Final Answer:** **The labor cost to install asphalt shingles at the high end of the scale is approximately \(\boxed{\$640}\) per square foot.** --- **Note:** If the actual hourly labor rate differs or if the total area is provided, you can adjust the calculation accordingly.
