Answer: $ 48
Explanation:
1) kw-h is a measure electric energy consumption.
2) The cost of electric energy is considered proportional to the number of kw-h (kilo watts - hour) consumed. Thi is:
cost------- = constant = unit cost = 0.40 $/kw-h
kw-h
3) Then, the total cost is the total number of kw-h times the unit cost. This is:
8 h × 15,000 watts × 1 kw / 1,000 watts × 0.40 $ / kw-h = $48.
That is the cost to charge the robot each night
