You can put this solution on YOUR website!
I really want to respond with a solution, but 56% saline or salt will NOT happen. Amanda does NOT have 56% saline. You have been given a very bad example, but what you want to do is probably something like this:\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "u = how much low concentration saline to use, 8%
\n" ); document.write( "v = how much high concentration saline to use, 56%?
\n" ); document.write( "8 gallons is how much 20% saline wanted\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( " $\"%288%2Au%2Bv%2A56%29%2F8=20\"$ and $\"u%2Bv=8\"$
\n" ); document.write( "... and you would solve for u and v.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Note too that densities would be very significant for any realistic problem of this type, and you would need to account for densities, since you seem to have w/w or w/v percent concentrations \n" ); document.write( "

\n" );
