Question 548196
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/(215-2(15))}}}
{{{18000/(215-30)}}}
{{{18000/(185)}}}
{{{97.297}}}

85%=x
{{{18000/(215-2(85))}}}
{{{18000/(215-170)}}}
{{{18000/(45)}}}
{{{400}}}
