For every shirt a tailor makes for a shop, he earns $40. On the other hand, for every shirt that he damages, he will have to pay the shop $15. Last week, for every 30 shirts he made, he damaged 5 shirts. He earned $64.75 from the shirts he made.
\n" ); document.write( ":
\n" ); document.write( "The last statement does not make any sense. His earned amt has to be a lot more and a multiple of $5
\n" ); document.write( ":
\n" ); document.write( "Anyway here is how I would do it.
\n" ); document.write( ":
\n" ); document.write( "Let x = shirts made
\n" ); document.write( "let y = shirts damaged
\n" ); document.write( ";
\n" ); document.write( "\"Every 30 shirts he made, he damaged 5 shirts.\" an equation for this:
\n" ); document.write( "\"x%2Fy\" = \"30%2F5\"
\n" ); document.write( "Cross multiply
\n" ); document.write( "5x = 30y
\n" ); document.write( "x = \"30y%2F5\"
\n" ); document.write( "x = 6y
\n" ); document.write( ":
\n" ); document.write( "40x - 15y = ??
\n" ); document.write( "Substitute 6y for x, find y
\n" ); document.write( "40(6y) - 15y = ??
\n" ); document.write( "240y - 15y = ??
\n" ); document.write( "225y = ??\r
\n" ); document.write( "\n" ); document.write( "(a) How many good shirts were made last week?\r
\n" ); document.write( "\n" ); document.write( "(b) How much less money did he earn because of the damage shirt?
\n" ); document.write( "
\n" );
