Chuck Sox makes wooden boxes in which to ship motorcycles. Chuck and his three employees invest a total of 40 hours per day making the 400 boxes. a) Their productivity \( =10 \) boxes/hour (round your response to two decimal places). Chuck and his employees have discussed redesigning the process to improve efficiency. Suppose they can increase the rate to 500 boxes per day. b) Their new productivity \( =12.50 \) boxes/hour (round your response to two decimal places). c) The unit increase in productivity is \( \square \) boxes/hour (round your response to two decimal places).

To determine the unit increase in productivity for Chuck Sox and his employees, we'll compare their new productivity rate to their original productivity rate. ### Given: - **Original Productivity (a):** 10 boxes/hour - **New Productivity (b):** 12.50 boxes/hour ### Calculation for Part (c): The **unit increase in productivity** is calculated by subtracting the original productivity from the new productivity. \[ \text{Unit Increase} = \text{New Productivity} - \text{Original Productivity} \] \[ \text{Unit Increase} = 12.50\ \text{boxes/hour} - 10\ \text{boxes/hour} = 2.50\ \text{boxes/hour} \] ### **Answer:** The unit increase in productivity is **2.50 boxes/hour**.
