Thank you for posting your question here at brainly. The amount will he owe next month if she makes no new purchases is $870.86. Subtract the minimum payment from the balance : $875.45 - $25.00 = $850.45. Then you add the interest charge which would be $21.41, as that is 2.4% of the new balance of $850.45. You add that which makes a new total balance of $870.86
