A 1500 W toaster is used for 4 hours. If the cost of electricity is K2.00 per KWh, what is the total cost of using the toaster?

Step 1: Convert the power from watts to kilowatts. P = 1500 W = 1500/1000 kW = 1.5 kW Step 2: Calculate the energy consumed in kilowatt-hours (KWh). E = P × t; E = 1.5 kW × 4 hours; E = 6 KWh Step 3: Calculate the total cost. Cost = E × Rate; Cost = 6 KWh × K2.00/KWh; Cost = K12.00 The cost of using the toaster is K12.00. K12.00

Convert the power from watts to kilowatts.
$P = 1500 \text{ W} = \frac{1500}{1000} \text{ kW} = 1.5 \text{ kW}$
Calculate the energy consumed in kilowatt-hours (KWh).
$E = P \times t$ $E = 1.5 \text{ kW} \times 4 \text{ hours}$ $E = 6 \text{ KWh}$
Calculate the total cost.
$\text{Cost} = E \times \text{Rate}$ $\text{Cost} = 6 \text{ KWh} \times \text{K}2.00/\text{KWh}$ $\text{Cost} = \text{K}12.00$
The cost of using the toaster is K12.00.
$\text{K}12.00$
