Otobai is  considering still another production method for its electric scooter. It  would require an investment of ¥15.10 billion in addition to the  initial investment of ¥15.10 billion but would reduce variable costs by  ¥42,000 per unit. The cost of capital was assumed to be 11%. The total  investment can be depreciated on a straight-line basis over the 10-year  period, and profits are taxed at a rate of 50%.
 
 Consider the following estimates for the scooter project.
 
 Market size	 	 	1.02	 million	 
 Market share	 	 	.1	 	 
 Unit price	 	¥	385,000.0	 	 
 Unit variable cost	 	¥	310,000.0	 	 
 Fixed cost	 	¥	3.02	 billion	 
 
 Assume investment is depreciated over 10 years straight-line and income is taxed at a rate of 50%.
 a.	What is the NPV of this alternative scheme? (Do not round intermediate  calculations. Enter your answer in billions. Round your answer to 2  decimal places.)
 
 Net present value	¥ 	 billion  
 b.	Calculate the break-even point. (Do not round intermediate calculations.  Round "PV Factor" to 6 decimal places and the final answer to the  nearest whole number.)
 
 Break-even point	  
 d.	Consider the following Preliminary cash-flow forecasts for Otobai's  electric scooter project (figures in ¥ billions). Calculate the variable  cost per year at which the electric scooter project would break even.  Assume that the initial investment is ¥15.10 billion. Investment is  depreciated over 10 years straight-line and income is taxed at a rate of  50%. Use Table 10.1. (Do not round intermediate calculations. Round  your answer to 2 decimal places.)
 
 Year 0	Years 1-10
 1.	Investment	15.1   	 
 2.	Revenue	 	39.27   
 3.	Variable cost	 	31.00      
 4.	Fixed cost	 	3.02      
 5.	Depreciation	 	1.51   
 6.	Pretax profit	 	3.74      
 7.	Tax	 	1.87   
 8.	Net profit	 	1.87   
 Operating cash flow	 	3      
 
 Net cash flow	-15    	3      
 
 Variable cost per year	¥   
 
 e.	Calculate the DOL. Consider fixed cost assuming the additional  investment of ¥15.10 billion. (Do not round intermediate calculations.  Round your answer to 2 decimal places.)
