In: Finance
present value of costs under purchase option
=25000+(300+400)*((1-(1+(6%/12))^(-5*12))/(6%/12))-10000/(1+(6%/12))^(5*12)
=53794.17
equivalent monthly cost under purchase option
=53794.17/((1-(1+(6%/12))^(-5*12))/(6%/12))
=1039.99 or 1040
from above equivalent monthly cost under purchase option of 1040 is less than the lease cost of 3000 per month, so purchase option alternative is less expensive
the above is answer..
