A manager uses the binomial 150t-150150t−150, where t is the expected high temperature, to approximate the number of visitors to a water park. She also uses the binomial \frac{1}{30}t-1 30 1 ​ t−1 to approximate the number of drinks each customer will buy. Which polynomial could she sue to approximate the total number of drinks that will sell with an expected high temperature t? 5t^2-155t-1505t 2 −155t−150 5t^2-145t-1505t 2 −145t−150 5t^2+145t+1505t 2 +145t+150 5t^2-155t+1505t 2 −155t+150
