I have got this :

price  = 300

p = newPrice - (price+170+newPrice*0.02+(newPrice*0.01)+25)

How would I solve newPrice so p = 100 ?

Thank you in advance ,

Let the new price be $q$.

Then $100=q-(300+170+0.02q+0.01q+25)=q-(495+0.03q)=0.97q-495$.

Hence $0.97q=595$ so $q=\frac{595\times 100}{97}=613.40$ to $2$ decimal places.
