Someone/something needs M gallons of mixture containing T% component. how many gallons each of material containing H% component and material containing L% component must be used to obtain the desired M gallons? \r

\n" ); document.write( "That is the general system. Solve for u and v. You can solve in general for this and general situations like this, and then substitute the values needed for any specific situation. \n" ); document.write( "
