Chris has two loans which both require payments to be made at the end of every week. With Loan 1 he borrowed $42663 and is repaying interest only. He will repay the principal after 6 years. With Loan 2 he borrowed $29485 and is repaying principal and interest each week over a period of 4 years. It is now 3 years since both loans were taken out and the interest rate continues to be 7.92% p.a.compounded weekly. What is the total amount Chris must pay this week?
