@Finn Hulse I hope you like this.First we need the equation E n e r g y = p o w e r × t i m e then calculate Energy= ( ( 1 0 + 2 ( 2 0 ) + 3 5 ) ÷ 1 0 0 0 ) × 2 4 h r s =2.04 so let us multiply by .1 to get the total amount of money per day Amount 2 . 0 4 × . 1 = . 2 0 4 Now we need to calculate the amount for 30 days so . 2 0 4 × 3 0 = 6 . 1 2 . I know this is too much for a solution but I want to be clear.
