At the beginning of the year Ryan had $60 in his car savings account. He plans to
deposit $30 into his account each month.
By the end of January he will have $90 in
his account, $120 by the end of February,
$150 by the end of March and so on. Write
a rule to describe this situation. Then, use
the rule to predict how much Ryan will have
in his car savings account at the end of two
years. Assume the account does not draw
any interest
