Hi, I have this: h=2C-34 where h is an amount of icecream being sold and C is temperature centigrade.
I also have this: 5/9F-32 where centigrade is converted to Fahrenheit.
So i can substitude the second formula in the first one: h=2(5/9F-32)-34
I get that, but the answer is: h= 10/9F + 14/9
Please anyone explain me how the 14/9 came about?
Thank you.
