An airport parking lot charges a base rate of $10.00 plus $7.00 for each additional night. Create a table to model the cost of parking a car in the lot for up to a week, then decide which type of function best models this situation.
1. Decide which two variables are being compared. 2. Decide which variable is independent, and which variable is the dependent variable. 3. Create a table of values for up to 7 nights in the lot. 4. Look for a pattern in the total cost by checking the first difference between dependent values. This applet is provided by Walch Education as supplemental material for their mathematics programs.
