Question

Prepaid off-peak call cost = R41,67 (rounded off) + R1.30 x airtime used. O 1 Time (in min) Prepaid costs Contract costs 0 41,67 108,42 10 54,67 108,42 20 30 67.67 80.67 108.42 C 40 50 93,67 107 108,42 108.42 60 B D 10214 . Use your completed table to draw a graph of the airtime in minutes versus the prepaid contract call costs on different sets of axes.​

Answer 1

Answer: I can provide you with the data in tabular format if you want to create the graph with the provided data.

Airtime (min) | Prepaid costs | Contract costs

0 | 41.67 | 108.42

10 | 54.67 | 108.42

20 | 67.67 | 108.42

30 | 80.67 | 108.42

40 | 93.67 | 108.42

50 | 102.14 | 108.42

60 | 114.64 | 108.42

This table shows the airtime (in minutes) used, and the corresponding costs for both prepaid and contract call plans. The prepaid costs are calculated using the formula: R41.67 + R1.30 x airtime used, whereas the contract costs are fixed at R108.42.

It's worth noting that the costs for the contract call plan is fixed and doesn't change with the airtime used, while for the prepaid plan the costs increase as the airtime increases.
