Exponential functions can be expressed as:
f=ir^t, f=final value, i=initial value, r=rate or common ratio, t=term number or "time" when it is fractional...In this case we have:
f=100((100-11)/100)^x
f=100(0.89)^x and we want to solve for when f=15 so
15=100(0.89)^x

160 test=100%
Therefore:
160 test------------------100%
