If u are going to check if the answers in the project are correct by using a calculator or solving in a paper, u will surely come up with a different answer in the project (especially in getting the fahreinheit there)...
Like in the 2nd line, u have a 46degree celsius given and the fahrenheit 78degrees as the answer but if u are going to convert it with a calculator... the fahrenheit should be 114.8
If you are wondering how i got this... use this formula....
c_to_f = ((9 * temp?)/5) + 32;
sir jouf used another formula like what i posted in the thread and that's
c_to_f = (9/5 * temp?) +32;
ill try to enforce this formula to sir jouf ASAP.
