    @James So, no books to buy for your course. Right? Just to confirm.

    James,

    Is this the proper place to ask questions about the lessons? This Blog page or e-mail you through contact us?

    Anyways, A.1.2 Problem #3. Is John earning money in years 1 and 3, while losing money in years 2, 4, and 5? I’m confused about the intrest and discount part. I wanted to see how $698.02 accumulated to $1,000. I did:

    1) 698.02*1.04 = 725.94
    2) 725.94*.95 = 689.64
    3) 689.64*1.06 = 731.02
    4) 731.02*.9 = 657.92
    5) 657.92*.9 = 592.13…

    I’m using the computer at my school and I can’t open the August study schedule. The lessons are opening fine.

    No. For (2) you are given d = .05. To accumulate using d you divide by 1-d. So it would be:

    698.02 * (1.04) * (0.95)^-1 * (1.06) * (0.9)^-2
