a credit card company charges 17% interest on any charges not paid at the end of the month. make a ratio table to show how much the interest would be for several amounts. if your bill totals $450 for this month, how much interest would you have to pay if you let the balance carry to the next month? show the relationship on a graph and use the graph to predict the interest charges for a $300 balance.

[charges][ $1 ][ $50}[ $100 ][ $200 ][ $450 ]
