Question 1185429
x  ounces of 1%
added to 100 ounces of 40%
to make 16% solution



{{{0.01x+0.4*100=0.16(x+100)}}}


{{{x+40*100=16(x+100)}}}

{{{x+40*100=16x+16*100}}}

{{{40*100-16*100=16x-x}}}

{{{100(40-16)=(16-1)x}}}

{{{highlight_green(x=100((40-16)/(16-1)))}}}, fairly easy to compute the value
