You are given the following information about an investment account:
Flura [38]

Answer:

The calculated dollar-weighted rate of return, Y = -25%.

Step-by-step explanation:

The time-weighted rate of return is 0%

Therefore, (12/10)*( X/(12 + X)) = 1

12X = 120 + 10X -> X = 60

The dollar-weighted rate of return,Y is calculated below as:

Y = (X-(10 + X))/(1*10+X/2)

Y = (60-(10+60))/(1*10+60/2)

Y = (60 - 70)/(10+30)

Y= -10/40

Y = -25%

Therefore, the calculated dollar-weighted rate of return, Y = -25%.
