John has a balance of $2000 on his Discover card that charges 2% interest per month on any unpaid balance. John can afford to pay $200 toward the balance each month. His balance each month after making a $200 payment is given by the recursively defined sequence Во - $200, В, - 1.028, -1 - 200 Determine John's balance after making the first payment. That is, determine B1. B, = $|
