How would you interpret the regression model? how would you interpret the coefficient for red sneakers?.

The sign of a regression coefficient tells you whether there is a positive or negative correlation between each independent variable and the dependent variable. A positive coefficient indicates that as the value of the independent variable increases, the mean of the dependent variable also tends to increase.

Step-by-step explanation:

There are several information's already given in the question. Based on those information's the answer can be easily arrived at. Let us first write down the details given.

Cost of a box of 10 wings = $7.00
Cost of a tray of nachos = $4.00
Amount that Freddy can spend is less that $40.
Then the equation will be

7x + 4y < 40

I hope the procedure is clear enough for you to understand.
