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 50°C, what is the temperature of the pot of water in °F?  Choose the correct choice:
A) 101°F B) 108°F C) 116°F D) 122°F E) 127°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(50)/5 + 32 = 122°F   The answer is 122°F.
