Thnk u Ham, but I knew that.. .. I have to show my work, and I keep going wrong somewhere. .. =(

hmm... not too sure how to do this without a converter. I can try though.

First, multiply everything by 5. You get 5f = 9c + 160. Subtract 160 from both sides and you get 5f - 160 = 9c.

Since you know what f is (100.94), plug that in for f. You then get 507.4 - 160 = 9c.

507.4 - 160 = 347.4. So, 347.4 = 9c. Then, divide everything by 9, and you get 38.6. Apparently google was off by .3 degrees.
