A diesel generator is needed to provide auxiliary power in the event that the primary source of power is interrupted. Various generator designs are available, and more expensive generators tend to have higher reliabilities should they be called on to produce power. Estimates of reliabilities, capital investment costs, operating and maintenance expenses, market value, and the damages resulting from a complete power failure are given in the table below. If the life of each generator is 10 years and the MARR is 10% per year, what is the total annual cost of alternative S if you assume three main power failures per year?

a.	-$77,500
	b.	-$86,522
	c.	-$98,066
	d.	-$108,660
	e.	-$94,082
