My apologies, I misunderstood the problem. Given that John deposits $35 each week and Mary's deposit function is y = $45x + $2800, we can see that Mary deposits $45 each week. Therefore, the correct statement comparing the rate of change for the two accounts would be:
Mary deposits $10 more each week than John.
