Question 868894: Hi,
i was wondering whether you were able to help me rearrange the following formula to find r;
No=150
C=450
N=C/(1+((C-No)/No))*e^-r*t
Thankyou!

N=C%2F%281%2B%28%28C-No%29%2FNo%29%29%2Ae%5E-r%2At
Rendering is failing on the equation. I see nothing wrong related to just the render-ability.

Including grouping specifically of -rt gives this when rendered:
N=C%2F%281%2B%28%28C-No%29%2FNo%29%29%2Ae%5E%28-r%2At%29
Multiply left and right sides by 1%2B%28C-No%29%2FNo.

N%281%2B%28C-No%29%2FNo%29=Ce%5E%28-rt%29

Multiply both sides by 1%2FC.
%28N%2FC%29%281%2B%28C-No%29%2FNo%29=e%5E%28-rt%29

ln%28%28N%2FC%29%281%2B%28C-No%29%2FNo%29%29=-rt

highlight_green%28r=%281%2Ft%29%2Aln%28%28N%2FC%29%281%2B%28C-No%29%2FNo%29%29%29, and then this is one of the ways to show the symbolic form of r, if the equation as shown is what you really intended. You can simply substitute the values you need and perform the computation for r.
