Four different examples are given below.

Example 1 In the newspaper, Mr. Shields read that the population of Jefferson County was decreasing at a rate of 20% every year.
Example 2 Alec is paid $200 each month to mow the grass and weed the garden. In addition, he earns $6.50 per hour for the number of hours he works as a dishwasher at the local diner.
Example 3 The PTA made $2,400 in ticket sales for their annual fundraiser.
Adult tickets, a, are $6.00 and children's tickets, c, are half price.
Example 4 In an arcade game, stars are based on the number of space aliens that are hit. For example, for the first alien, 1 star is given, for the second alien, 2 stars are given, for 3 aliens, 4 stars are given, for 4 aliens, 8 stars are given. Each star is multiplied by 100 to determine the players score.
Analyze each one, telling whether or not the example can be modeled by a linear or exponential function and tell any specific characteristics about each example (include common difference, common ratio, slope, etc.)
