Suppose that the cost of electrical energy is $0.12 per kilowatt hour and that your electrical bill for 30 days is $60.00. assume that the power delivered is constant over the entire 30 days. what is the power in watts?

690 W

Explanation:

A day has 24 hours, so a month has 24 × 30 = 720 hs

In a month whe spent a total of $60. 00, so per hour whe were  spending

$ per hour

We know the cost of one  is   so dividing the money spent in an hour among this value we get:

This power delivered is constant, so every moment it is

it doesn't. it was imagined up in the middle ages.
