The cost of operating the iron is $2186.49.

To find the answer, we have to know about the power.

How to find the cost of electricity?

  • We have the expression for cost of electricity as,

              [tex]cost=power(kW)*t(hours)*(price/ kWh)[/tex]

  • It is given in the question that, the cost per kWh is $0.10, the current is 5.2A, the voltage is 240V.
  • We have to find the cost for two years, before that, we have to find the power and it will be,

                        [tex]P=IV=5.2*240=1248W[/tex]

  • 2 years will be equal to

                     [tex]t=2*365*24hours=17520hours.[/tex]

  • Thus, the value of cost will be,

                  [tex]cost=1248*10^{-3}*17520*0.10} =\$2186.49[/tex]

Thus, we can conclude that the cost of operating the iron is $2186.49.
