You can put this solution on YOUR website!
An online music store sell songs for 2 different prices. Your dad buys you 43 songs for a total of $49.59.
\n" ); document.write( "The low cost songs are $0.99 each and the more expensive songs are $1.25 each. How many of each did he buy?
\n" ); document.write( ":
\n" ); document.write( "Using your equations
\n" ); document.write( "x + y = 43
\n" ); document.write( "x = (43-y); we can use this form for substitution
\n" ); document.write( ":
\n" ); document.write( ".99x + 1.25y = 49.59
\n" ); document.write( "from the 1st equation, we can substitute (43-y) for x, solve for y:
\n" ); document.write( ".99(43-y) + 1.25y = 49.59
\n" ); document.write( "42.57 - .99y + 1.25y = 49.59
\n" ); document.write( "-.99y + 1.25y = 49.59 - 42.57
\n" ); document.write( ".26y = 7.02
\n" ); document.write( "y = \"7.02%2F.26\"
\n" ); document.write( "y = 27 ea 1.25 cds
\n" ); document.write( ":
\n" ); document.write( "I know you can find x, the no. of .99 cds, now. check by finding the total cost \n" ); document.write( "
\n" );
