The model of the table is shown below:

Step 2:

The equation of the model is

y = 140.6t + 371.6

Step 3:

To predict the number of people infected in 15 days, substitute t = 15

$\begin{gathered} y\text{ = 140.6 }\times\text{ 15 + 371.6} \\ \text{y = 2109 + 371.6} \\ \text{y = 2480}.9 \\ y\text{ = 2481} \end{gathered}$

Final answer

2481
