For this case we must take into account the following unit transformations:
 [tex]1 year = 365 days 1 day = 24 hours 1 kw = 1000 w[/tex]
 Applying the unit transformation we have:
 [tex](3) * (1/1000) * (24) * (365) = 26.28 kw * h [/tex]
 Then, the cost is given by:
 [tex]C = (26.28) * (0.0900) C = 2.3652 $[/tex]
 Answer:
