Let's solve this step by step:

1. Completing the missing numbers in the table:
- A = 60.0
- B = 3.0
- C = 1.0
- D = 3.2

So, the table now looks like this:
[tex]\[ \begin{tabular}{|l|c|c|c|c|c|c|c|} \hline Number of students & 1 & 2 & 3.0 & 4 & 1.0 & 12 & 15 \\ \hline Number of cars washed & 60.0 & 30 & 20 & 15 & 6 & 3.2 & 4 \\ \hline \end{tabular} \][/tex]

2. If six students are working, how many cars will each one have to wash?
- Each of the six students will wash 22.5 cars.

3. How many students will be used if each student only washes TWO cars?
- 15 students will be used.

4. Is the graph an example of direct or indirect proportion? Justify the answer.
- The graph is an example of direct proportion because the number of cars washed increases uniformly with an increase in the number of students.

5. Name the dependent and the independent variables.
- The number of cars washed is the dependent variable.
- The number of students is the independent variable.

The students are charging R50 per car for washing services.
