Step 1 For minimum number of sales:  dS(t)dt=0
 d(5.8t2  81.2t + 1200)dt=0
 11.6t  81.2=0
 11.6t=81.2
 t=81.211.6
 t=7

Step 2

So, minimum number of sales is given by  S(7)=5.8(7)2  81.2(7) + 1200
 S(7)=284.2  568.4 + 1200
 S(7)=915.8
 S(7) = 916

Aurora is planning to participate in an event at her school's field day that requires her to complete tasks at various stations in the fastest time possible. To prepare for the event, she is practicing and keeping track of her time to complete each station. The x-coordinate is the station number, and the y-coordinate is the time in minutes since the start of the race that she completed the task. (1,3),(2,6),(3,12),(4,24)
Part A: Is this data modeling an algebraic sequence or a geometric sequence? Explain your answer.
Part B: Use a recursive formula to determine the time she will complete station 5.
Part C: Use an explicit formula to find the time she will complete the 9th station.
