Yesterday, two friends went into a bank to open savings accounts. Nellie started by putting $50 in her account, and she will deposit an additional $455 each week. Malia made no initial deposit, but she will add $460 more each week. In a few weeks, the friends will have the same account balance. How many weeks will that take? What is that account balance?
a) 6 weeks, $3500
b) 7 weeks, $3955
c) 8 weeks, $4410
d) 9 weeks, $4865
