    Need help on this one.

    If the percent of adult height attained by a 5 to 15 year old girl can be modeled by f(x) 62+35log10(x-4), where x is the age in years and f(x) is the percent. At age 14, what percent of her adult height has a girl reached?

    Please show me the steps so I won't get confused.

    f(x)=62+35 \log(x-4)

    f(14)=62+35 \log(14-4)

    f(14)=62+35 \log(10)

    f(14)=62+35(1)

    f(14)=97
