L=Lia's collections, P=Phil's collections C=Cam's collections \n" ); document.write( "P=L+$12.80, C=3L, L+P+C=$200.30 \n" ); document.write( "Substitute for P and C and solve for L \n" ); document.write( "L+P+C=$200.30 \n" ); document.write( "L+(L+$1280)+3L=$200.30 \n" ); document.write( "5L+$12.80=$200.30 Subtract $12.80 from both sides \n" ); document.write( "5L+$12.80-$12.80=$200.30-$12.80 \n" ); document.write( "5L=$187.50 divide both sides by 5 \n" ); document.write( " L=$37.50 ANSWER 1 Lia collects $37.50 \n" ); document.write( "P=L+$12.80 \n" ); document.write( "P=$37.50+$12.80=$50.30 ANSWER 2 Phil collects $50.30 \n" ); document.write( "C=3L \n" ); document.write( "C=3($37.50)=$112.50 ANSWER 3 Cam collects $112.50 \n" ); document.write( "CHECK: \n" ); document.write( "L+P+C=$200.30 \n" ); document.write( "$37.50+$50.30+$112.50=$200.30 \n" ); document.write( "$200.30=$200.30 \n" ); document.write( " |
