Theresa has $1.75 in quarters and nickles. If she has 15 coins total, how many quarters does Theresa have?
\n" ); document.write( "--------------
\n" ); document.write( "Quantity Eq: n + q = 15 coins
\n" ); document.write( "Value Eq: 5n+25q = 175 cents
\n" ); document.write( "--------------------------------
\n" ); document.write( "Divide thru the Value Eq. by 5.
\n" ); document.write( "---
\n" ); document.write( "n + q = 15
\n" ); document.write( "n +5q = 35
\n" ); document.write( "----------------
\n" ); document.write( "Subtract and solve for \"q\":
\n" ); document.write( "4q = 20
\n" ); document.write( "q = 5 (# of quarters)
\n" ); document.write( "------------------------
\n" ); document.write( "Solve for \"n\":
\n" ); document.write( "n + q = 15
\n" ); document.write( "n + 5 = 15
\n" ); document.write( "n = 10 (# of nickels)
\n" ); document.write( "===========================
