H= p * at , (H = p*a^t)
Please help with this equation, p, will be the value of 125 and "a" will be the growth factor of 5,so how many home will be built for H at any three value of time, t, in years that I would like to use , not sure

You have written two entirely differnt equations. You probably are suppose4d to use the second one. Then they tell you what p, a and t are.
You should be able to use the equation to predict the number of homes built. They need to tell you if this formula gives the cumulative number of homes built since year 0, or the nummber of hoimes built per year.
