Extracted text: Preet wants to purchase a new dress for wedding at a cost of $1200 plus 12% tax. She can afford to make monthly repayments of $85 and has two credit options. a) The first is to use the store credit card which charges 21.3% annual interest, compounded daily on outstanding balances, but offers to pay 12% tax on the dress. b) Her other option is her bank credit card which charges 14.9% annual interest, compounded daily. The card does not have an outstanding balance. By how much is one of the options less expensive than the other?
