To determine the exact percentage of the labor time required for the 16th unit compared to the 1st unit, we can use the concept of the learning curve. The learning curve formula often used in such cases is:

$Y = A \times X^b$

Where:

• $Y$ is the time required to produce the $X$th unit.
• $A$ is the time required to produce the 1st unit.
• $X$ is the unit number.
• $b$ is the learning curve exponent, calculated as $b = \log(L) / \log(2)$, where $L$ is the learning rate.

Given dataTo determine the exact percentage of the labor time required for the 16th unit compared to the 1st unit, we can use the concept of the learning curve. The learning curve formula often used in such cases is:

$Y = A \times X^b$

Where:

• $Y$ is the time required to produce the $X$th unit.
• $A$ is the time required to produce the 1st unit.
• $X$ is the unit number.
• $b$ is the learning curve exponent, calculated as $b = \log(L) / \log(2)$, where $L$ is the learning rate.

Given

• Time for the 1st unit: $22,000$ hours
• Time for the 2nd unit: $15,400$ hours
• Time for the 4th unit: $10,780$ hours
• Time for the 8th unit: unknown
• Time for the 16th unit: unknown

Step 1: Determine the learning rate

The learning rate $L$ is found by comparing the time for the 2nd unit to the 1st unit:

$L = \frac{\text{Time for 2nd unit}}{\text{Time for 1st unit}} = \frac{15,400}{22,000} \approx 0.7$

Step 2: Calculate the learning curve exponent $b$

$b = \frac{\log(L)}{\log(2)} = \frac{\log(0.7)}{\log(2)} \approx -0.5145$

Step 3: Calculate the time for the 16th unit

Now, using the learning curve formula:

$Y_{16} = 22,000 \times 16^{-0.5145}$

Let's calculate $Y_{16}$.

$Y_{16} \approx 22,000 \times 0.397 = 8,734 \text{ hours}$

Step 4: Determine the percentage of the 16th unit compared to the 1st unit

$\text{Percentage} = \frac{Y_{16}}{Y_{1}} \times 100 = \frac{8,734}{22,000} \times 100 \approx 39.7\%$

So, the time required to produce the 16th unit is approximately 39.7% of the time required to produce the 1st unit.
