Answer:
9.4%
Step-by-step explanation:
Initial investment=$22,000+$22,000=$44,000
number of shares bought=$44,000/$110(the investor paid $55 out of every $110)
number of shares bought=400
Increase in share in one year=$110*8%=$8.80
loan interest on each share=$55*6.6%=$3.63
rate of return=(increase in share price-loan interest)/initial amount invested
rate of return=($8.80-$3.63)/$55
rate of return=9.4%
