A potential home buyer is wondering about her credit card accounts and the effect that they may have on her credit score which will be evaluated when she applies for a mortgage loan. At present, she has three accounts with credit limits and balances outstanding as follows: She would like to transfer the balance in account #2 to account #3 in order to save the membership fee and because the interest charges for account #2 are higher than the others. If she does this account #2 would be closed. Account (1) Limit $ 5,000 15,000 15,000 Outstanding Balance $3,700 5,700 8,700 (2) (3) Required: a. How much credit capacity is she currently using? b. If she cancels account #2 and transfers the balance to account #3, what will be the capacity used now? C. After the transfer, how much would an increase in the total credit limit have to be in account #3 to restore the total capacity used in all accounts prior to the transfer
