Growth
Fertilizer purchases a gravity settling tank by borrowing the $50000 purchase
price. The loan is to be repaid with four equal annual payments at an annual
compound rate of 15%. It is anticipated that the tank will be used for 9 years
and then sold for $3000. Annual operating and maintenance expenses are
estimated to be $9000/year increasing by $500 per year thereafter. Savings of
$15000/year are estimated over the present filtration system increasing by 3%
per year thereafter. The firm uses a MARR
of 15% for its economic analyses. Perform a sensitivity analysis to determine
the effects on the economic feasibility of the plan due to errors in estimating
the annual operating and maintenance costs as well asthe savings. Use a range of (-30% +30%) with
intervals of 10%.
