Beth Zion Hospital has received initial certification from the state of California to become a center for liver transplants. The hospital must complete its first 10 transplants under great scrutiny and at no cost to the patients with the hospital picking the expenses. The cost per hour is estimated to be $5200. The very first transplant, just completed, required 32 hours. On the basis of research at the hospital, Beth Zion estimates that it will have an 80% learning curve. Using the following table, estimate the time it will take to complete:

	75%		80%		85%
Unit Number	Unit	Total	Unit	Total	Unit	Total
(N)	Time	Time	Time	Time	Time	Time
10	.385	5.589	.477	6.315	.583	7.116
