To determine the cost for 45 kWh of electricity, follow these steps:
1. Identify the relevant tariff:
According to the municipal tariff table, the cost per kWh for the range of 0 to 50 kWh is R 0.7986.
2. Calculate the total cost:
Since 45 kWh falls entirely within the 0 to 50 kWh range, multiply the number of kilowatt-hours (kWh) by the cost per kWh.
[tex]\[
\text{Total Cost} = \text{Number of kWh} \times \text{Cost per kWh}
\][/tex]
3. Substitute the values:
[tex]\[
\text{Total Cost} = 45 \text{ kWh} \times R 0.7986 \text{ per kWh}
\][/tex]
4. Compute the final cost:
[tex]\[
\text{Total Cost} = R 35.937
\][/tex]
5. Round to two decimal places:
The total cost, rounded to two decimal places, is:
[tex]\[
R 35.94
\][/tex]
Thus, the cost for 45 kWh of electricity is [tex]\( R 35.94 \)[/tex].
