Your Turn $6-3$:

$1]$ One design for new windmill complex costs $$9$ million to construct, will

produce $$15$ million worth of power, and will require $$2$ million in

operating and maintenance costs. A second design will cost $$6$ million

to construct, produce $$10$ million worth of power, and will require $$2$

million in operating and maintenance costs. Find the net benefits,

benefit$/$cost ratio, and percentage rate of return on each of these two

projects.

Project $1$: net benefits $=$

benefit$/$cost ratio $=$

rate of return$=$

a Project $2$: net benefits $=$

benefit$/$cost ratio $=$

rate of return$=$

a Which option is best according to each measure?
