Unformatted text preview: equation P = 140n  8500, where n is the number of hard drives sold. Graph P = 140n  8500 for n < 1000. Estimate the profit, to the nearest ten dollars, corresponding to the sale of 875 hard drives. P = 140*8758500 = P = 1225008500 = $114,000.00 P = $114,000.00 Estimated profit of the sale of 875 hard drives will be $114,000. 5. When $8500 is invested in a savings account paying simple interest for the year, the interest, i in dollars, can be obtained from the equation i = 8500r , where r is the rate of interest in decimal form. Graph i = 8500r , for r up to and including a rate of 16%. If the rate is 12%, how much interest is earned? If the rate is 16%, how much interest is earned? Interest = 8500*0.16 = $ 1,360 r = 0.12 Interest = 8500*0.12 = $ 1,020 REFERENCES: Bittinger, M. L., & Keedy, M. L. (1988). Essential Algebra with Problem Solving.
