Answer:
11.7%
Step-by-step explanation:
Calculation to determine What were the dollar-weighted rates of return
Dollar-weighted rates of return=$500,000 + $500,000/(1 + r)
Dollar-weighted rates of return= $75,000/(1 + r) + [($500,000+500,000)+(10%*$500,000+$500,000)]/(1 + r)^2
Dollar-weighted rates of return= $75,000/(1 + r) + $1,100,000/(1 + r)^2
Dollar-weighted rates of return= 11.7%;
Therefore The Dollar-weighted rates of return is 11.7%
