Answer
Number of People (N) | Cost for Catering (C)
--- | ---
1 | R30
2 | R60
3 | R90
4 | R120
5 | R150
6 | R180
3.2 **Independent Variable:** Number of people (N)
**Dependent Variable:** Cost for catering (C)
Solution
Since Thembi charges R30 per head, the cost is found by multiplying the number of people by 30. The table can be completed as follows:
Number of People (N) Cost for Catering (C)
1 R30
2 R60 (i)
3 R90 (ii)
4 R120 (iii)
5 R150 (iv)
6 R180 (v)
3.2 The independent variable is the number of people (N) because it is the variable that you choose or control. The dependent variable is the cost for catering (C) because it depends on (or is “dependent on”) the number of people attending.

To complete the missing values in the table, we can see that the cost for catering (C) is calculated by multiplying the number of people (N) by the price per head, which is R30. So for two people, C would be R60 (R30 x 2), and the values would continue as such: - For 1 person: R30 - For 2 people: R60 - For 3 people: R90 - For 4 people: R120 - For 5 people: R150 The dependent variable is the cost for catering (C), since it depends on the number of people (N), which is the independent variable. If you want to keep everyone happy at your function, it's a good idea to factor in a little extra for that unexpected party crash!
