(i) Calculate her monthly payment. Adelaide needs a printer for his new office. The cost of the printer is R 15000 . This is much too expensive for Adelaide to pay at once, so she opts for a hire purchase agreement, whereby she will have to pay a deposit of \( 15 \% \) of the cost and pay back the balance, plus \( 18 \% \) p.a. simple interest, by means of monthly payments over a period of 5 years. Adelaide works out that she can afford the deposit and can manage to pay a maximum of R500 per month. Will she be able to afford the deal?

What is \( \frac{16}{100} \) as a decimal?

4. Algunos empleados de la empresa Ciudad Bonita necesitan urgente (y no pueden salir a tomar medidas), conocer la distancia que separa las bases de un poste y de una columna de alumbrado, cuya lảmpara, ubicada a 3 metros de altura, produce con el poste mencionado, de 1,5 metros de altura, una sombra de 12 metros. ¿Pueden averiguar la medida con los datos que tienen? De ser así, ¿cuánto medirá esa distancia?

3. If \( x-2=7 \), then \( x= \) \( \begin{array}{ll}\text { A. } 5 & \text { B. } 7\end{array} \)

A new washing machine uses \( 40 \% \) less water than an older model. A family used 1,200 gallons of water per month to run the old washing machine. About how much water will they use each month to run the new washing machine? A 580 gal B 360 gal C. 840 gal
