Dr. seus asked:
Between her home mortgage, car loan, and credit card bill, Megan is $75,300 in debt. The monthly interest on her credit card is 1.5%, the monthly interest on her car loan is 1%, and the monthly interest on her mortgage is 0.6%. After one month, her total accumulated interest is $460.50. If the interest on Megan’s credit card bill was $4.50 more than the interest on her car loan, find the amount of each loan.
