Bianca is a stockbroker. Her earnings are based on a graduated commission. She receives 3% on any stock sale up to $100,000 and 5% for any amount over the $100,000. Last Saturday she sold $110,000 worth of stocks. How much did she make selling the stocks? A. $3700 B. $3000 C. $5000 D. $3500

Bianca sold $110,000 worth of stocks
which mean = 100,000 + 10,000

For  0.03  on any stock sale up to $100,000
And 0.05  for any amount over the $100,000

∴ She made selling the stocks = 100,000 * 0.03 + 10,000 * 0.05
                                                 = 3000 + 500
                                                 = 3500

So, the right answer is option D
