| In order to manage water usage for the future a study was done in Australia on how households in the City West Water (CWW) area and Yarra Valley Water (YWW) area used water for residential purposes during the winter and the summer. The table in ANNEXURE C shows how 26 households in the study used water during the winter and the summer when they showered. |

QUESTION 4
4.1
| Maria, her husband and child live in Harrismith. They are planning a sightseeing family trip to Springbok to see the flowers. They want to rent a motorhome (see ANNEXURE D) to drive to Springbok. They will use this motorhome for transportation and accommodation. They estimate that the total return distance they will travel is 3 050 km. They have to budget for the vehicle rental, vehicle insurance and fuel. |
Use the information above and ANNEXURE D to answer the questions that follow.
4.1.1 The family is considering renting the two-berth (sleeper) vehicle. They do not want to pay an excess (extra amount) in case of an accident.
- Calculate the average rental cost per person if they rent the vehicle for 8 days using the unlimited kilometre option. (4)

4.1.3 The price of diesel is RI 1,78 per litre. Maria stated that renting the two-berth vehicle instead of the four-berth vehicle would save RI 278,84 on the fuel cost for the trip.
Verify Maria's statement by showing ALL calculations. (10)
4.2
| The family finally decided to rent the smaller motorhome. Maria used the regional map and distance chart in ANNEXURE E to plan their trip to Springbok.
