The ratio of Julio's money to Marcus's money was 7:10. After Julio bought 4 books at $4.50 each the ratio of Julio's money to Marcus's money was 1:4. Use a bar graph to find how much money Julioo and Marcus have left.
\n" ); document.write( "----
\n" ); document.write( "Original amounts of money
\n" ); document.write( "Julio has 7x dollars
\n" ); document.write( "Marcus has 10x dollars
\n" ); document.write( "------
\n" ); document.write( "Julio spent 4*4.50 = 18 dollars on books.
\n" ); document.write( "---
\n" ); document.write( "Equation:
\n" ); document.write( "(7x-18)/10x = 1/4
\n" ); document.write( "---
\n" ); document.write( "28x - 72 = 10x
\n" ); document.write( "18x = 72
\n" ); document.write( "x = 4
\n" ); document.write( "---
\n" ); document.write( "Julio has 7x-18 = 28-18 = 10 dollars
\n" ); document.write( "Marcus has 10x = 40 dollars
