There are 36 coins in a purse, all nickels and quarters. There are 8 more quarters than nickels. The total amount is $6.20. How many nickels and quarters are there?
\n" ); document.write( "---------------------
\n" ); document.write( "Equations:
\n" ); document.write( "Quantity Equation: n + q = 36
\n" ); document.write( "Value Equation::::5n +25q = 620 cents
\n" ); document.write( "============================================
\n" ); document.write( "Multiply thru the Quantity Equation by 5 to get:
\n" ); document.write( "5n + 5q = 5*36
\n" ); document.write( "---
\n" ); document.write( "Subtract that from the Value equation to get:
\n" ); document.write( "20q = 620-5*36
\n" ); document.write( "20q = 440
\n" ); document.write( "q = 22 (number of quarters)
\n" ); document.write( "----
\n" ); document.write( "Substitute into n+q=36 to solve for \"n\":
\n" ); document.write( "n = 36-22 = 14 (number of nickels)
\n" ); document.write( "=====================================
