To calculate the cost per degree of heating:
\[ CPDH = \frac{EC}{T} \]
Where:
A cost per degree of heating is the amount of money spent to raise the temperature of a room by one degree. This will depend on the size of the room, cost of electricity, insulation of the room, and the efficiency of the heater.
Let's assume the following values:
Step 1: Divide the total cost of electricity by the total change in temperature:
\[ CPDH = \frac{100}{20} = 5 \text{ dollars per degree} \]
