Calculate the total water cost for the Ndlovu family, given their consumption and the municipality's water tariff structure.

Here are the solutions to your questions. 2.1 The municipality that supplies water to the Ndlovu family is Walter Sisulu Municipality. 2.2 A tariff in this context refers to the rate or price charged by the municipality for a unit of water consumed. 2.3 The first 6 kl of water usage is free as it is a basic human right to have access to a certain amount of free water, often provided by municipalities to ensure essential needs are met. 2.4 Step 1: Calculate the cost for each block of water usage. The Ndlovu family used 27 kl of water. Block 1 (0 - 6 kl): Volume used: 6 kl Tariff: R0.00/kl Cost: 6 kl × R0.00/kl = R0.00 Block 2 (6 - 10.5 kl): Volume used: 10.5 kl - 6 kl = 4.5 kl Tariff: R17.37/kl Cost: 4.5 kl × R17.37/kl = R78.165 Block 3 (10.5 - 35 kl): Remaining volume used: 27 kl - 10.5 kl = 16.5 kl Tariff: R23.87/kl Cost: 16.5 kl × R23.87/kl = R394.055 Step 2: Calculate the total cost by summing the costs from each block. Total Cost = R0.00 + R78.165 + R394.055 Total Cost = R472.22 The Ndlovu family will pay R472.22. 2.5 Two ways the Ndlovu family can save water are: • Taking shorter showers instead of baths. • Fixing any leaking taps or toilets promptly. 3 done, 2 left today.
