Andisiwe and her husband, Thobela, have a $20-$year home loan on a house in

Boson, Bellville since the end of $2010.$ The size of the loan was R$2\mathrm{.}575$ million

and the interest rate was $14\mathrm{.}25\%$ p$.$a$.$ compounded monthly. Assume that they

paid, every month, the minimum required instalment from the start. Also

Assume that the interest will remain the same for the entire term. Assume that

today is May $10,2024.$ Also assume that all payments are at the end of the

month. If Andisiwe and Thobela will continue with the monthly minimum

payment, how much will they have paid over the $20$ years?
