The resale value of a textbook decreases by 25% with each previous owner. A new textbook is sold for $85. Which function represents the resale value of the textbook after x owners? (x) = 85 (1 - 0.25) x

f (x) = 85 (1 + 0.25) x

f (x) = 85 (0.25) x

f (x) = (85 - 0.25) x

    A exponential function would represent it nicely f (x) = b*a^x

    Reason being a decrease of %

    a = 1+r

    r = - 25% = - 0.25

    And b being what the original cost of the book

    f (x) = 85*0.75^x

    Where f (x) is the price after x amount of previous owners
