Final answer:
The equation to represent Jordan's college savings over time is A = 325 + 50t, where A is the total amount saved and t is the number of months of saving.
Step-by-step explanation:
Jordan wants to start saving for college by adding money to an existing account. To represent Jordan's savings over time, we can create a linear equation that considers Jordan's initial savings and his monthly contributions. Let A be the total amount saved after t months. The initial amount in the account is $325, and Jordan adds $50 each month. Therefore, the equation is A = 325 + 50t, where t is the number of months Jordan has been saving.
