    Exponential Graph help? (Word Problem) 1

    A corporate jet originally costs $16,550,000. If its value depreciates by 5 percent per year, what will its value be after 10 years?

    I don't have an answer, though I thought I did..

    T(x) = T(0)(1+x)^n

    T(x) is the value at any given value of n
    T(0) is the value at x=0 (ie original value)
    x is the factor of depreciation (x>0 for inflation)
    n = number, in this case years.

    plug in your numbers,
    T(0) = 17,550,000
    x = -0.05
    n = 10

    T(t) = 17550000\cdot(1-0.05)^10 = 10,507,833.28
