A study of air quality in a particular city by an environment group suggests that t years from now, the level of carbon mnoxide, in parts per million, in the air can be modeled by the function A(t)=0.2t²+0.1t+5.1. What will the level be (in parts per million) three years from now? How many years from now will the level of carbon monoxide be at 8 parts per million? Round to the nearest tenth hundredth.
