Question

Dixie Dynamite Company is evaluating two methods of blowing up old buildings for commercial purposes over the next five years. Method one (implosion) is relatively low in risk for this business and will carry a 11 percent discount rate. Method two (explosion) is less expensive to perform but more dangerous and will call for a higher discount rate of 16 percent. Either method will require an initial capital outlay of $93,000. The inflows from projected business over the next five years are shown next.  
  

Years	Method 1			Method 2
1	$	35,700		$	23,200
2		45,900			24,100
3		50,500			37,800
4		42,500			37,700
5		21,900			77,500

   
Use Appendix B for an approximate answer but calculate your final answers using the formula and financial calculator methods.

a. Calculate net present value for Method 1 and Method 2. (Do not round intermediate calculations and round your answers to 2 decimal places.)
  

Answer 1

Method 1:

NPV = Present valueofcas inflows - present value of cash flows

NPV = -93,000 + 35,700 / (1 + 0.11)^1 + 45,900 / (1 + 0.11)^2 + 50,500 / (1 + 0.11)^3 + 42,500 / (1 + 0.11)^4 + 21,900 / (1 + 0.11)^5

NPV = -93,000 + 32,162.16216 + 37,253.46969 + 36,925.16476 + 27,996.0664 + 12,996.58408

NPV = $54,333.45

Method 2:

NPV = Present valueofcas inflows - present value of cash flows

NPV = -93,000 + 23,200 / (1 + 0.16)^1 + 24,100 / (1 + 0.16)^2 + 37,800 / (1 + 0.16)^3 + 37,700 / (1 + 0.16)^4 + 77,500 / (1 + 0.16)^5

NPV = $26,847.22
