According to the formula F=9/5 (C) +32, if the temperature in degrees Farenheit (F) increases by 30, by how much does the temperature in degrees Celsius (C) increase? Pick.
A) 9  B) 16.66  C) 47  D) 48 3 / 5  E) 59

Rationale: "you can plug in values . c = 5 / 9 * ( f - 32 ) f = 32 - - > c = 0 ; f = 32 + 30 = 62 - - > c = 5 / 9 * 30 = 16.66 . increase = 16.66 degrees . answer : b ."
Answer: B
