Answer:
Type A is 7%, type b is 11%
Step-by-step explanation:
We have these two firm's as type a and type b
For type A
Interest would be = risk Free rate of 2% + risk free rate of 5% = 7%
For type B
= Risk free rate of 5% + risk free rate of 6% = 11%
I would use the average of this two 9% as interest but this is not going to work for type A because this interest rate is too high. People won't want to pay this much.
