last part of both questions please give the right answer with the right number (many get it wrong)

The following table summarizes cash flows for a project: a. Choose the appropriate expression you need to solve to find the IRR(s) for this set of cash flows. Do not solve. A. $5,250+$3,000(P/F,i,1)+$4,000(P/F,i,2)$1,500(P/F,i,3)=0 B. $3,000+$3,000(P/F,1,1)+$3,000(P/F,1,2)$3,000(P/F,i,3)=5 c. $5,250+$3,000(A/P,1,1)+$4,000(A/P,1,2)$1,500(A/P,i,3)=0 D. There is no expression that can be used. b. What is the maximum number of solutions for the IRR that could be found in part (a)? The maximum number of solutions for the IRR is 2 . (Round to the nearest whole number as needed.) c. You have found that an IRR of 14.48 percent solves the expression in part (a). Compute the project balances for ear (Type an integer or decimal rounded to two decimal places as needed.) Sam is considening buying a now lawnmower. He has a choice between a Lawn Guy mower and a Bargain Joe's Cip Job mower. The salvage value of each mower at the end of its service life is zero. Find which altervative is profernble using the RRR method and a MARR of 5 percent Assume that one of the allematives must be chosen. Answer the following questions by using present worth computations to find the IRRis. Use the least common muttple of service lives. a. What are the cash fows for each year of the comparison period (i.e., the least common multiple of service lives)? b. Are you able to conclude that there is a single IRR on the incremental invesiment? Why or why not? c. Which of the two alternatives should be chosen? Use the ERR method if necessary. a.
