A \( \$ 160,000 \) mortgage is to be repaid over a 20-year period by end of the month payments rounded up to the next-higher \( \$ 100 \) Interest is \( 5.44 \% \) compounded semi-annually. (a) Determine the number of rounded payments required to repay the mortgage. (b) Determine the size of the last payment. (c) Calculate the amount of interest saved by rounding the payments up to the next-higher \( \$ 100 \).

A lawnmower was traded in for \( R 236 \) after 10 years. The depreciation was calculated at \( 9,2 \% \) p.a. on a straight-line basis. Determine the cost of the lawnmower 10 years ago.
