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].
