A student's bank account is represented in the table shown. Create a linear regression equation that can be used to model the amount of money in the account (the balance), y, based on the time (in weeks), x. Round all values to the nearest hundredth.

Use the model to approximate the amount in the account after 15 weeks. Round to the nearest hundredth.

Use the model to approximate how long it would take to have $50.00 in the account.
