Answer:
a) first we have to calculate the terminal value at year 5:
terminal value = ($245 x 1.04) / (12% - 4%) = $254.8 / 8% = $3,185
year cash flow
1 $120
2 $145
3 $176
4 $199
5 $245 + $3,185 = $3,430
Using a financial calculator, the enterprise value = $2,420.75
b) again, using a financial calculator, the discount rate at which the enterprise value is $3,000 would be 6.8423%
