Step 1: Determine the meter number. The meter number is explicitly stated on the till slip under "Meter:". The meter number is 07032985769. Step 2: Determine the missing value, B. The total amount paid is the sum of the electricity cost and the VAT. Total = Electricity + VAT R1 300,00 = R1 130,43 + B To find B, subtract the electricity cost from the total. B = R1 300,00 - R1 130,43 B = R169,57 The missing value B is R169,57. Step 3: Determine the number of kWh units Mieecke purchased. The cost of electricity excluding VAT is R1 130,43. We use the tariff table to find the units. First, calculate the cost for Block 1 (0-350 kWh) at R2,19/kWh: Cost for Block 1 = 350 kWh × R2,19/kWh Cost for Block 1 = R766,50 Since the total electricity cost (R1 130,43) is greater than the cost for Block 1 (R766,50), Mieecke purchased units in Block 2 as well. Next, calculate the remaining cost for electricity that falls into Block 2: Remaining cost = Total electricity cost - Cost for Block 1 Remaining cost = R1 130,43 - R766,50 Remaining cost = R363,93 Now, calculate the number of units purchased in Block 2 using the tariff of R2,91/kWh: Units in Block 2 = Remaining costTariff for Block 2 Units in Block 2 = R363,93R2,91/kWh Units in Block 2 = 125 kWh Finally, calculate the total number of kWh units purchased: Total kWh units = Units in Block 1 + Units in Block 2 Total kWh units = 350 kWh + 125 kWh Total kWh units = 475 kWh The number of kWh units Mieecke purchased is 475 kWh.
