The number of time (in hours) the dryer was operated is equal to 58.93 hours.

Given the following data:

  • Power = 4400 Watts
  • Electricity costs = 5.6¢/kWh
  • Consumption cost = 75¢

To determine the number of time (in hours) the dryer was operated:

The cost of energy consumption.

First of all, we would convert the value of power in Watts to Kilowatts.

Conversion:

1000 Watts = 1 Kilowatts

4400 Watts = 4.4 Kilowatts

Next, we would determine the total cost of energy consumption:

[tex]Total\;cost = Power \times cost\\\\Total\;cost =4.4 \times 75[/tex]

Total cost = 330¢

Now, we can calculate the time this dryer was operated:

[tex]Time =\frac{330}{5.6}[/tex]

Time = 58.93 hours.
