1. The problem statement, all variables and given/known data The problem states that you discovered the body at 1pm Thursday in a freezer where the temperature was 10F. Temperature of the corpse at discovery was 40F. I have to find how many hours ago the victim died. 2. Relevant equations You are given the formula T = Ta + (98.6 - Ta)(0.97)^t where Ta is air temperature. 3. The attempt at a solution So I plugged the numbers in: 40 = 10 + (98.6-10)(0.97)^t but I have no idea how to solve for t. Any help?
