Final answer:

Sales predictions on day 60 and day 90 are 250.12 and 324.52 thousand dollars respectively, calculated by plugging the day value into the given regression model.

Step-by-step explanation:

To predict the sales using the given model, we simply plug in the value of x (the day) into the equation and calculate.

Day 60 Prediction

Ô˙˭ = 101.32 + 2.48 * 60

First, calculate the multiplication part: 2.48 * 60 = 148.8.

Then, add this to 101.32 to find the total: 101.32 + 148.8 = 250.12. Therefore, the sales prediction for day 60 is Ô˙ = 250.12 thousand dollars.

Day 90 Prediction

Ô˙ = 101.32 + 2.48 * 90

First, calculate the multiplication part: 2.48 * 90 = 223.2.

Then, add this to 101.32 to find the total: 101.32 + 223.2 = 324.52. Therefore, the sales prediction for day 90 is Ô˙ = 324.52 thousand dollars.
