Suppоse yоu аre trying tо build а regression model to predict/explаin an individual’s credit card balance (CC Balance). You are thinking of including the following x-variables to help explain CC Balance: Family Size, Weekly Food Spending, Number of Vehicles Owned, and Monthly Housing Spending.

Explain what that means (in the context of the problem). What would you do to solve the multicollinearity problem?
