I'm not even sure of how to go about this problem. But its for Average daily balance method. The problem is: "Lance's credit card statement for July showed these items: 7/1, previous balance, $54.69; 7/4, purchase $29.94; 7/9, purchase, $145.32; 7/15, purchase $79.19; and 7/29, payment, $200. Lance's card company uses a 3.4% monthly periodic rate and the average daily balance method including new purchases. What is Lance's financial charge for July and his new balance?"
