Please help with this! Jen is deciding to get a new phone. One deal is a free phone with a two year contract, but she will have to pay the sales tax of 8% on the original price of $399 and the monthly charge is $10 more than she currently pays. The other is on sale for $199, plus 8% sales tax. The monthly charge is the same as what she currently pays. Over the two year contract period, which phone will be the lower cost and by how much?
