Suppose that x and y are related by the equation 30x+450=y . Answer the questions below. What is the change in the amount of money in the account? What was the starting amount of money in the account?

I agree, it appears that "y" is the total amount of money in the account.  Diane would have started with $450 and puts $30/week in the account.
