NOTE:
Watts and megawatts are measures of power (the rate/speed at which energy is used or delivered).
That means that people are billed for the amount of energy used in . That is power multiplied by time.
My electric bill is in kilowatt-hour in the USA,
y era en kilovatios-hora cuando yo vivía en Sudámerica.
An increase of 4% per year meas that as a 4% of the previous cost is added,
the new cost becomes 100% + 4% = 104% of what it was before.
In other words, cost gets multiplied times every year.
Starting at per unit of energy,
after 5 years it would be
.
I would round that to , because 36.499587072 is less than 36.50.
