a) Step 1: Determine the range for STEP 2. STEP 2 covers water consumption from > 6 k up to 10,5 k. Step 2: Calculate the number of kiloliters in STEP 2. Kiloliters in STEP 2 = 10,5 k - 6 k = 4,5 k The number of kiloliters in STEP 2 is 4,5 k. b) Step 1: Identify the consumption range for 17 k. • STEP 1: 0 6 k • STEP 2: > 6 10,5 k • STEP 3: > 10,5 35 k • STEP 4: > 35 k Since 17 k is greater than 10,5 k but less than or equal to 35 k, it falls within the range of STEP 3. The last step charged for 17 k is STEP 3. c) Step 1: Calculate the cost for each consumption step for 17 k. • For STEP 1 (0 k to 6 k): Volume = 6 k Rate = R 17,51/k Cost_1 = 6 k × R 17,51/k = R 105,06 • For STEP 2 (> 6 k to 10,5 k): Volume = 10,5 k - 6 k = 4,5 k Rate = R 24,39/k Cost_2 = 4,5 k × R 24,39/k = R 109,755 • For STEP 3 (> 10,5 k to 17 k): Volume = 17 k - 10,5 k = 6,5 k Rate = R 34,63/k Cost_3 = 6,5 k × R 34,63/k = R 225,095 Step 2: Calculate the total water bill. Total water bill = Cost_1 + Cost_2 + Cost_3 Total water bill = R 105,06 + R 109,755 + R 225,095 Total water bill = R 439,91 The Adams family has to pay R 439,91 for the 17 k of water used. d) Step 1: Calculate the sewerage removal charge. The sewerage removal is calculated at a rate of 70\% of the total water bill. Sewerage charge = 70\% × Total water bill Sewerage charge = 0,70 × R 439,91 Sewerage charge = R 307,937 Rounding to two decimal places: Sewerage charge = R 307,94 They were charged R 307,94 for the sewerage. e) Step 1: Calculate the total water and sewerage bill. Total bill = Total water bill + Sewerage charge Total bill = R 439,91 + R 307,94 Total bill = R 747,85 Their total water and sewerage bill was R 747,85. Send me the next one 📸
