Example 1 MONEY Nina has a new job. She spends $2 every day on coffee. Define a variable. Then write a function rule that relates the total amount of money Nina spends on coffee to the number of days at work. Determine the function rule. The amount of money spent depends on the number of days at work. Let x represent the number of days at work.
