The cost of the electricity if 42000 kWh of electricity is used is ;  $1680
<h3>Determine the cost of electricity </h3>
<u>Given that ;</u>
value of electricity used = 42000 kWh 
cost rate of electricity = $0.04/kWh 
 
Final step : Determine the total cost of electricty used 
unit cost = $0.04/kWh 
Totals cost = unit cost * value of electricity used 
                   = 0.04 * 42000 = $1680
Hence we can conclude that The cost of the electricity if 42000 kWh of electricity is used is ;  $1680.
