Example 3, continued

The first unit of a new product is expected to take 100 hours. An 80% learning
curve is known to apply.

(d) If the steady state is reached at 20 units, how long does it take to make
the first 30 units?

Total time to make the first 20 units = 762.48 hours (from part (c))

Time to make the remaining units = time to make the 20th unit × (30 –
20)

Time to make the remaining units = 26.06 (from part c) × 10 = 260.60
