suppose your local electric company charges $0.0650/kWxh for the first 200.0 kWxh, and then drastically raises the price for every kilowatt-hour more. What is the maximum you family would pay if they wanted to pay only the cheaper rate?
200 kW-h multiplied but the lower rate, 0.065 $/kW-h.
The answer will be in dollars. Although the problem does not say so, these are probably monthly billings.
