The formula is F= 35e^-0.7p
make p the subject.
Thanks in advance I am not sure where to start.
You "undo" what has been done to p.
The last thing done on the left is "multiply by 35" so the first thing you do to solve for p is divide both sides by 35:
Now, we have an exponential function (e to a power). The reverse of that is the "natural logarithm". Take the logarithm of both sides:
Finally, p is multiplied by -0.7. Divide both sides by -0.7:
