Gravity is a bit different on Mars. A rock is kicked off the surface of Mars. It reaches a maximum height of 96.15ft after 3.85 seconds and then lands back on the surface 7.7 seconds after it was kicked. Determine the equation of the flight of the rock in standard form.

R(t) = -1.03 +7.11t - 0.30t,
where R is revenue in billions of dollars and t represents the year with t = 0
corresponding to the year 1980. In what year will revenue be maximum?
