For this case we must take into account the following unit transformations:
1 year = 365 days

1 day = 24 hours

1 kw = 1000 w

Applying the unit transformation we have:
(3) * (1/1000) * (24) * (365) = 26.28 kw * h

Then, the cost is given by:
C = (26.28) * (0.0900)

C = 2.3652 $

the cost of operating a 3.00-w electric clock for a year is:
C = 2.3652 $
