Step-by-step explanation:
Lets consider sales revenue to bethe dependent variable and, type of sport, color, and target audience, the categorical variables represented with dummy variables. Just remeber that one fewer dummy variables than the number of options in a category must be used, so, type of sport should be represented by: 3 - 1 = 2 dummy variables
color should be represented by 5 - 1 = 4 dummy variables, and
target audience should be represented by 2 - 1 = 1 dummy variables
This totalizes: 2 + 4 + 1 =7 independent variables.
