Answer:


\text{ \$}214.50

Step-by-step explanation:

Here, we want to get the amount incurred by running appliances and refrigeration

Firstly, we need to calculate the KWh used by these activities

This is 13% of the total

Thus, we have that as:


(13)/(100)*\text{ 11,000 = 1,430 kWh}

To get the cost of this, we have to multiply by $0.15

Mathematically, we have that as:


0.15\text{ }*\text{ 1430 = \$214.50}
