Jeff Sellers bought 200 shares of radio shack stock at $22.35. eight months later,he sold the stock at $31.76.assuming a 2% commission charge, what is the bottom line for Jeff?

200 * 22.35 = 4,470
200 * 31.76 * 0.98 = 6,224.96
Subtract his purchase price from his sales price.

ms. sue, is it $ 1,754.96? Thanks

It's not clear from your question whether the commission is charged once or twice (at purchase and at sale). Assuming the latter (which is customary)...
Cost basis: (22.35 * 200) * 1.02 = $4,559.40
Sale proceeds: (31.76 * 200) * (1  0.02) = $6,224.96
Net profit: 6,224.96  4,559.40 = $1,665.56
8 month return: 1665.56 / 4559.40 = 36.53%
