The battery on your phone is almost dead. When you plug it in to charge, you only have 3% battery left.

Suppose that your phone charges at a rate of 2% every minute.

Construct a table of values to show your percent battery charge at 0, 5, 10, and 15 minutes.

 A parking lot has a fixed rate which is as follows: for the first hour or fraction is charged $ .95, and for each hour or additional fraction is charged $ 0.50. 

 1. Build the function by pieces that determines the amount of money to collect for the hours or fraction of having used the parking lot. 2. How much money do you charge a person who parks for two hours and fifteen minutes? 3. Construct the graph of the function obtained in the first part part.
