I am sorry, but I don’t understand. Wish I could help
Total cost for the trip = $800.
Let x = original number of friends.
Therefore the equally shared cost of the trip for each friend is $800/x.
After 2 friends drop out, the cost for each friend increases to $800/(x-2).
The increase in cost for each remaining friend is $20, therefore

Divide through by 20.

Cross multiply.
x(x - 2) = 80
x² - 2x - 80 = 0
(x + 8)(x - 10) = 0
x = -8 or 10
Reject x = -8 because we cannot have a negative number for friends.
x = 10
Answer: There were 10 friends in the original group.

Answer:
13.05%
Explanation:
Using CAPM Equation, Ke = Rf+Beta*(Rm-Rf)
= 0.045+1.3*(0.07)
= 0.136
= 13.60%
Using Dividend growth model, Ke = (D1/P0) + g
= (D0*(1+g)/P0) = g
= (1.50*(1+0.08)/36) + 0.08
= 0.125
= 12.50
The cost of equity (Ke) = 0.136 + 0.125 / 2
The cost of equity (Ke) = 0.261/2
The cost of equity (Ke) = 0.1305
The cost of equity (Ke) = 13.05%
