Help with 29 please! Thank you!

Kayla has a balance of $1479 on her credit card. Since she is unable to pay off the balance in full at the end of the month, the credit card company will charge her 2% interest per month on the outstanding balance at the end of each month. She plans on paying $X each month until the card is paid off in full. Write a recursive rule for Kayla's credit card balance a_n. after the credit card company charges her the monthly interest. To the nearest dollar, find the value of X that will hold the card balance steady at $1479 after interest. Kayla is considering whether to pay the card off at a rate of S65 per month or $130 per month. For each monthly payment, find the number of months required to pay the card off in full, and the total amount paid. (you may wish to use your calculator or a spreadsheet program.)
