Please answer 2. b)

Suppose a researcher in IUT would like to undertake a project on energy generation for fuel-cell systems that are hydrogen and methanol-based. During a lab research, three equal-service machines need to be evaluated economically. The MARR is 10% per year. Perform the present worth analysis and select the best machine type with the costs shown in a Table below. Give reason/s. The annual equivalent costs have two components, namely capital costs and operating costs. Now, the capital recovery costs can be found by CR(i%)=I(A/P,i%,n)S(A/F,i%,n)=(IS)(A/P,i%,n)+iS Given: I=$20,000,S=$4,000,n=5yr, and i=10%. Evaluate applying the above formulas and see if an annual revenue of $4,400 is large enough to cover the capital costs or need additional revenue. Draw the necessary cash flow diagrams.
