Answer:
Assuming that the company uses the incremental learning curve method, the total labor cost for 4 units will be closest to 13 hours
Step-by-step explanation:
a. According to the given data we have the following:
The first job takes 40 hours.
The next job takes 32 hours.
So total hours for first 2 jobs = 40+32 = 72
Average cost for first 2 jobs = 72/2 = 36
Learning rate = 36/40 = 90%
Therefore, the average for 4 jobs (double of 2 jobs) shall be 36*90% = 32.40 hours
Hence, Total hours for 4 jobs = 32.40*4 = 129.60 hours or close to 130 hours.
Assuming that the company uses the incremental learning curve method, the total labor cost for 4 units will be closest to 13 hours
