Answer 1

130.38622

Step-by-step 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
