Agraduated commission employee makes 3.5% interest on the first $50,000 in sales and 6.5% interest on all sales over $50,000. which of the following expressions represents the employee’s total earnings on $81,500 in sales? a. (0.035)(50,000) + (0.065)(81,500) b. (0.035)(50,000) + (0.065)(31,500) c. (0.35)(50,000) + (0.65)(31,500) d. (3.5)(50,000) + (6.5)(31,500)

 Your answer is B. (0.035)(50,000) + (0.065)(31,500)

Not A because this part of the expression (0.065)(81,500) includes the total price of everything, not just the sales over $50,000. Not C because the percentages aren't written correctly, and not D for the exact same reason. A percentage is written over one-hundred. For example, 5% is written as 5/100 in fraction form and 0.05 in decimal form. 5.6% is 5.6/100 or 0.056, etc, etc.
