Suppose that sales (in dollars) are directly related to an advertising campaign according to , where t is the number of weeks of the campaign. Find the rate of change of sales after 8 weeks and interpret your answer. Round your answer to two decimal places.

A) -2.25. So, during the 9th week, the model predicts that sales will decrease approximately $2.25.
B) -24.79. So, during the 9th week, the model predicts that sales will decrease approximately $24.79.
C) -2.25. So, during the 9th week, the model predicts that sales will increase approximately $2.25.
D) -24.79. So, during the 9th week, the model predicts that sales will increase approximately $24.79.
E) 0. So, during the 9th week, the model predicts that sales will remain constant.
