What do you know...you know that:
\n" ); document.write( "Cost of one dozen roses = $30
\n" ); document.write( "You can buy 7 dozen roses + 4 single roses = cost of 64 single roses\r
\n" ); document.write( "\n" ); document.write( "You want to know the cost of a single rose and the total amount of money you have.\r
\n" ); document.write( "\n" ); document.write( "If X = the cost of a single rose and $30 = the cost of a dozen roses, then your equation is:
\n" ); document.write( "7($30) + 4X = 64X\r
\n" ); document.write( "\n" ); document.write( "Simply and solve for X.
\n" ); document.write( "$210 + 4X = 64X
\n" ); document.write( "$210 + (4X - 4X) = 64X - 4X
\n" ); document.write( "$210 = 60X
\n" ); document.write( "$210/60 = 60X/60
\n" ); document.write( "$3.50 = X
\n" ); document.write( "Therefore, the cost of a single rose is $3.50.
\n" ); document.write( "Now input that cost into the original equation to get the total amount of money you have to spend.\r
\n" ); document.write( "\n" ); document.write( "7($30) + 4($3.50) =
\n" ); document.write( "$210 + $14
\n" ); document.write( "$224\r
\n" ); document.write( "\n" ); document.write( "Check your answer:
\n" ); document.write( "64 individual roses = 64($3.50) or $224.00\r
\n" ); document.write( "\n" ); document.write( "The cost of a single rose is $3.50 and you have $224.00 to spend on roses.\r
\n" ); document.write( "
