Answer:
Initial net worth = $40* 500= $20000
a) Net worth of brokerage account = 44 * 500 = $22000
Percentage increase in the net worth of your brokerage account=[22000-20000]/20000 * 100= 10%
b) Net worth of brokerage account = 40 * 500 = $20000
Percentage increase in the net worth of your brokerage account=[20000-20000]/20000 * 100= 0%
c)If XTel's price changes to $36, the net worth of the brokerage account can be calculated as follows:
Net worth of brokerage account = 36 * 500 = $18,000.
Percentage decrease in the net worth of your brokerage account=[18000-20000]/20000 * 100= -10%
