While speaking on the phone to a friend in Oslo, Norway, you learned that the current temperature there was 23 Celsius (23C). After the phone conversation, you wanted to convert this temperature to Fahrenheit degrees F, but you could not find a reference with the correct formulas. You then remembered that the relationship between F and C is linear. (a) Using this and the knowledge that 32F = 0 C and 212F = 100C, find an equation that computes Celsius temperature in terms of Fahrenheit temperature; i.e., an equation of the form C= "an expression involving only the variable F ." (b) Likewise, find an equation that computes Fahrenheit temperature in terms of Celsius temperature; i.e. an equation of the form F= "an expression involving only the variable C ." (c) How cold was it in Oslo in F?
