Water boils at 212°F or 100°C and ice melts at 32°F or 0°C . If the temperature of a pot of water is 40°C, what is the temperature of the pot of water in °F?
Choose the correct choice from the following choices
A) 85 °F  B) 92 °F  C) 96 °F  D) 99 °F  E) 104 °F
Let F and C denote the temperature in Fahrenheit and Celsius respectively.   (F - 32) /(212 - 32) = (C - 0)/(100 - 0)   F = 9C/5 + 32   F = 9(40)/5 + 32 = 104°F   The answer is 104 °F.
