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

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?

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

Right?
