Hi,I have a linear model with equation p = 5.1t - 28, where p is the number of breeding pairs of birds and t is the year. I need to use algebra to find the year in which the linear model predicts the breeding pairs will exceed 500.

Any help appreciated.

    Solve the equation

    5.1t - 28 = 500

    5.1t = 472

    t = 472/5.1 = ___ years

    Looks like a long wait.

    I am assuming that "year zero" is the year when p = 28, and the counting starts. It is not 1 AD

    Si, I'm assuming you meant the number of years it takes for the breeding pairs to exceed 500

    P = 5.1t -28 = 500 Solve for t:
    t = 528 / 5.1 = 103.5 or 104 yrs..

    Yes. I agree with your answer.
