You can put this solution on YOUR website!
This is a ratio: If 30% was taken off, that means that $171.50 was the remaining 70%\r
\n" ); document.write( "\n" ); document.write( "70% out of 100% = $171.50 out of how much?\r
\n" ); document.write( "\n" ); document.write( "70/100=171.50/x\r
\n" ); document.write( "\n" ); document.write( "yiou then cross multiply the fractions to get\r
\n" ); document.write( "\n" ); document.write( "70(x)=(100)(171.50)
\n" ); document.write( "70x=17150\r
\n" ); document.write( "\n" ); document.write( "divide both sides by 70 and you get\r
\n" ); document.write( "\n" ); document.write( "x=245\r
\n" ); document.write( "\n" ); document.write( "the original price was $245\r
\n" ); document.write( "\n" ); document.write( "(***To check your answer, check what 30% of 245 is and then subtract the 30% from the original price that you got, ie:\r
\n" ); document.write( "\n" ); document.write( "245(.30) = 73.5
\n" ); document.write( "30% of 245 is 73.5\r
\n" ); document.write( "\n" ); document.write( "245 - 73.5 = 171.5 <-- if this is what was posed in the originial question (which it is) then you're right.) \n" ); document.write( "
