You can put this solution on YOUR website!
if you can convert 15% to .15 then the equation is using the #% and not the decimal form
so simply plug in the % for x and solve
I did the first and the last one you should be able to do the rest on your own
15%=x
18000%2F%28215-2%2815%29%29
18000%2F%28215-30%29
18000%2F%28185%29

85%=x
18000%2F%28215-2%2885%29%29
18000%2F%28215-170%29
18000%2F%2845%29
