You can put this solution on YOUR website!
Let r be the rate at which Ryan works. Then Eric would be r+1. Then you have:
\n" ); document.write( "1/r+1/(r+1)=1/4
\n" ); document.write( "4(r+1)+4r=rē+r
\n" ); document.write( "rē-7r-4=0
\n" ); document.write( "Using the quadratic formula; we get r=7.53112887415, or -0.531128874149. Throwing out the negative result, It would take Ryan 7.53112887415 hours and Eric 8.53112887415 hours working alone to fill 100 orders. ☺☺☺☺
