\n" ); document.write( " You work at a grocery store. Your hourly wage is greater after 6:00 p.m, than it is during the day. One week you work 20 daytime hours and 20 evening hours and earn $280. Another week you work 30 day time hours and 12 evening hours and earn a total of $276. What is your daytime rate? What is your evening rate?\r

You can put this solution on YOUR website!
Let D = day time rate and E = evening rate.\r
\n" ); document.write( "\n" ); document.write( "\"20%28D%29+%2B+20%28E%29+=+280\" and
\n" ); document.write( "\"30%28D%29+%2B+12%28E%29+=+276\" Multiply the 1st equation by 3 and the 2nd equation by 2.\r
\n" ); document.write( "\n" ); document.write( "\"60D+%2B+60E+=+840\" and
\n" ); document.write( "\"60D+%2B+24E+=+552\" Now subtract the 2nd equation from the 1st equation.\r
\n" ); document.write( "\n" ); document.write( "\"36E+=+288\" Divide both sides by 36.
\n" ); document.write( "\"E+=+8\" Substitute this into 2nd equation and solve for D.\r
\n" ); document.write( "\n" ); document.write( "\"20D+%2B+20%288%29+=+280\"
\n" ); document.write( "\"20D+%2B+160+=+280\" Subtract 160 from both sides.
\n" ); document.write( "\"20D+=+120\" Divide both sides by 20.
\n" ); document.write( "\"D+=+6\"\r
\n" ); document.write( "\n" ); document.write( "Daytime rate is $6.00 per hour.
\n" ); document.write( "Evening rate is $8.00 per hour.\r
