2. Marli planned to invest equal amounts into a savings account on 1 December 2014 and on 1 December 2015 to have accumulated an amount of R 7110 by 1 December 2016. If this account earns interest at \( 12 \% \) p.a. compounded annually, how much money should Marli deposit into the account on each occasion?

\( \left. \begin{array} { l } { A = - 2 , D = - 3 , C = - 4 , D = 5 } \\ { - d B - 4 C - 4 D + 4 A = } \end{array} \right. \)

2. The cost for electricity varies directly with the amount of kilowatt hours of electricity used. The cost for using 1,079 kilowatt hours of electricity was \( \$ 129.48 \). What was the cost for using 908 kilowatt hours of electricity?

55. A rational number between \( \frac{1}{4} \) and \( \frac{3}{4} \) is \( \begin{array}{lll}\text { (a) } \frac{1}{5} & \text { (b) } \frac{4}{5} & \text { (e) } \frac{1}{2}\end{array} \)

Solve system of linear equations \( \mathrm{A} \mathrm{x}=\mathrm{b} \), where \( A=\left(\begin{array}{ll}1 & 2 \\ 2 & 1\end{array}\right), b=\binom{4}{3} \)
