Suppose that the height (in centimeters) of a candle is a linear function of the amount of time (in hours) it has been burning. After 10 hours of burning, a candle has a height of 22 centimeters. After 27 hours of burning, its height is 20.3 centimeters. What is the height of the candle after 13 hours?

Suppose you receive $100 for a graduation present, and you deposit it in a savings account. Then each week thereafter, you add $5 to the account but no interest is earned. The amount in the account is a function of the number of weeks that have passed. Create an equation that represents that situation.
