I'm more sophisticated than my little sister so I save my money in a bank account that pays me
3% interest on the money in the account at the end of each month. (If I take my money out
before the end of the month, I don't earn any interest for the month.) I started the account with
$50 that I got for my birthday. Use a table, a graph, and an equation to create a mathematical
model of the amount of money I will have in the account after m months.
