Algebra-equation to model balloon's elevation as function of time (t)

    Algebra--equation to model balloon's elevation as function of time (t)

    1. The problem statement, all variables and given/known data

    Balloon takes off from a location 158ft. above sea level. it rises 56 ft/min.

    Please help me write an equation to model balloon's elevation h as function of time t

    2. Relevant equations



    3. The attempt at a solution

    t=158h + 56

    Let's take this one step at a time. You know the formula for modeling something that changes with time is F(t) = Changing Variable times t + Initial State, right?

    If you know the Initial State (Height) of the Balloon, then what else needs to be placed in the function?

    Set F(t) to the height.
    Set time to t.
    Set Initial State to 158.

    So far we got h = ??? + 158

    What are we missing?

    Thanks for your reply.

    What is missing in the equation is 56 ft./min.
    Then, the ans could be
    h= 56t + 158

    Right?
