She makes a profit of $10 on each turntable $6 on each cassette. Both must go through two steps in her shop - assembly and bench checking. A turntable take 12 hours to assemble and 4 hours to bench check. A cassette player take 4 hours assemble and 8 hours to bench check. Looking at this month's schedule, Sally sees that she has 60 assembly hours uncommitted and 40 hours of bench-checking time available. Find her best combinations of turntables and cassette player.

12t + 4c = 60 assemble

\n" ); document.write( "-2t - 4c = -20
\n" ); document.write( "10t = 40
\n" ); document.write( "t = 4 and c = 3
\n" ); document.write( "| 4($10) + 3($6) = $58 \n" ); document.write( "
