Liam borrowed a total of $35,000 to pay for college. he pays his parents 3% interest on the $8,000 he borrowed from them and pays the bank 6.8% on the rest. what average interest rate does he pay on the total $35,000? (round your answer to the nearest tenth of a percent.)

Liam pays an average interest of 5.9% on the total $35,000.

Since the amounts borrowed and the respective interest rates are different, the weighted average will give us a better picture of the average interest paid on the loan.

We calculate weights based on the total amount borrowed.

                             Borrowing ($)                  Weights

Parents                     3000             = 0.228571429

Bank                       32000           = 0.771428571

Total                       35000                                                                     1

Once we have the weights, we multiply the interest rates with the respective weights. Then we find the total of the (weights * Interest rate) column to find the weighted average or the average rate Liam pays.

Parents       0.228571429      0.03  

Bank           0.771428571       0.068
