Answer:
130.38622
Explanation:
The model that best fits the data is the quadratic model with the equation
S(t) = 0.104084t² + 1.38443t - 4.82228
Then, to predict the net sales in 2020, we need to replace t by 30. This is because t = 5 is corresponding to 1995 and 2020 is 25 years after 1995, so t = 5 + 25 = 30 correspond to 2020.
So, replacing t = 30, we get
S(t) = 0.104084(30)² + 1.38443(30) - 4.82228
S(t) = 130.38622
Therefore, the answer is 130.38622
