Thanks Click to expand... so we have: \(\displaystyle w \, = \, \frac{100}{\frac{p}{c}+1}\) isolate 'p' to the left-hand-side \(\displaystyle \frac{p}{c}+1 \, = \, \frac{100}{w}\) isolating further \(\displaystyle \frac{p}{c} \, = \, \frac{100}{w} \, - \, 1\) \(\displaystyle \frac{p}{c} \, = \, \frac{100 \, - \, w}{w} \,\) now finish it......
