What is the answer for a
a= 15.22(0.5) 2/5.7

Net Proceeds = Selling Price - Total Cost Price

a. Samantha

Total Cost Price;

Bought shares for d dollars and paid 2% commission = d + (d * 2%) = 1.02d

Selling Price;

Sold stock for s dollars and paid flat fee of $11 = s - 11

Net Proceeds = (s - 11) - 1.02d

b. Alex

Total Cost Price;

Bought x dollars worth and paid 1% commission = x + (x * 1%) = 1.01 * x = 1.01x

Selling Price;

Value falls to y and Alex pays 1.25% when he sells = y - (y * 1.25%) = y - 0.0125y = 0.9875y

Net Proceeds = 0.9875y - 1.01x
