Section B
Question 4
The Ngobeni family uses 𝑥 𝑙𝑖𝑡𝑟𝑒𝑠 of water per day. Use the given information to answer the following questions:
The Ngobeni family uses 3850 𝑚𝑙 of water per day for cooking and drinking, 90 𝑙 per day for bathing, 105 𝑙 per day in the shower, they wash dishes in the sink which uses 3100 𝑚𝑙, they run two loads of washing which uses 70 𝑙 of water per load, and they use 76 𝑙 to flush the toilet. 1 𝐾𝑖𝑙𝑜𝑙𝑖𝑡𝑟𝑒 = 1000 litres
