3 items cost d dollars each. In total, they cost 3d dollars\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Let's cay she pays c dollars in cash.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "The amount of change is the difference in the two: c - 3d\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "we know this change is $8, therefore, c-3d = 8\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Isolate c: \r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "c-3d = 8\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "c-3d+3d = 8+3d\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "c = 3d + 8\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "The final answer is 3d + 8\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Side note: we have NOT factored in taxes of any kind \n" ); document.write( "
