Re: In which month was the electric energy cost per Fahrenheit [#permalink]
2
Remember that "per" means divide. Thus, the electric energy cost per Fahrenheit degree = the electric energy cost / Fahrenheit degree.

We are asked what the least value of that fraction is. A fraction is small when the numerator is small and the denominator is high. So we want the average temperature to be high and the energy cost to be low.

If you look at the graph, only in May in November does the temperature exceed the cost, and in May this difference is significantly larger. Hence, the answer is May (B).
