Solve.A scientist is growing a colony of bacteria for an experiment. The number of bacteria in the colony can be modeled by the quadratic expression 17x2 - 882x + 14,640, where x is the number of days since the scientist began the experiment. Using this model, after how many days would we expect to find 67,000 bacteria in the colony? Round to the nearest whole day.
A. 97 days B. 45 days C. 87 days D. 35 days
