He lost 6 of his 176 lbs in 45 days.
\n" ); document.write( "6/176=3/88
\n" ); document.write( "(3/88)(1/45)=1/1320 of his weight lost per day.
\n" ); document.write( ".
\n" ); document.write( "let x be wt. before diet.
\n" ); document.write( "x-(15x/1320)=176
\n" ); document.write( "1305x/1320=176
\n" ); document.write( "x=176*1320/1305=178 lbs weight before diet.
\n" ); document.write( ".
\n" ); document.write( "Let d=days it takes before he loses 11 more lbs.
\n" ); document.write( "176*d/1320=11
\n" ); document.write( "176d=11*1320=14520 multiply each side by 1320 to eliminate fraction.
\n" ); document.write( "d=14520/176=82.5 days
