A grapefruit is tossed straight up with an initial velocity of 50 ft/sec. The grapefruit is 7 feet above the ground when it is released. Its height at time t is given by y=161² +50r + 7. How high does it go before returning to the ground? Round your answer to one decimal place. The maximum height of the grapefruit is i feet.
