Calculate the amount of water used by the Soduku family from 13 June to 14 July 2025.

Question 2.1 2.1.1 Calculate the amount of water used by the Soduku family from 13 June to 14 July 2025. Step 1: Identify the meter readings for the given dates. The meter reading on 14 July 2025 was 1321 kL. The meter reading on 13 June 2025 was 1235 kL. Step 2: Calculate the difference between the final and initial readings to find the water used. Water used = Meter reading on 14 July 2025 - Meter reading on 13 June 2025 Water used = 1321 kL - 1235 kL Water used = 86 kL The amount of water used is 86 kL. 2.1.2 Verify whether Mr Soduku's claim is valid. Mr Soduku claims the bill for the month will be R1 200. We need to calculate the actual cost for 86 kL of water based on the provided tariff structure. Step 1: Break down the total water used (86 kL) according to the tariff blocks. • First 6 kL: 6 kL at 904 cents/kL • Next 4 kL (from 7 to 10 kL): 4 kL at 1027 cents/kL • Next 10 kL (from 11 to 20 kL): 10 kL at 1335 cents/kL • Remaining kL (above 20 kL): 86 kL - (6+4+10) kL = 86 kL - 20 kL = 66 kL at 1639 cents/kL Step 2: Calculate the cost for each block. • Cost for first 6 kL: 6 × 904 = 5424 cents • Cost for next 4 kL: 4 × 1027 = 4108 cents • Cost for next 10 kL: 10 × 1335 = 13350 cents • Cost for remaining 66 kL: 66 × 1639 = 108174 cents Step 3: Sum the costs from all blocks to get the total cost in cents. Total cost in cents = 5424 + 4108 + 13350 + 108174 Total cost in cents = 131056 cents Step 4: Convert the total cost from cents to Rands. Since 1 Rand = 100 cents: Total cost in Rands = (131056)/(100) Total cost in Rands = R1310.56 Step 5: Compare the calculated cost with Mr Soduku's claim. Mr Soduku claims the bill will be R1 200. The calculated bill is R1 310.56. Since R1 310.56 is not equal to R1 200, Mr Soduku's claim is not valid. Mr Soduku's claim is not valid. Send me the next one 📸
