$\"x\"$ = number of $5 bills Katie has
\n" ); document.write( " $\"x%2B4\"$ = number of $20 bills Katie has
\n" ); document.write( " $\"5%2Ax\"$ = value, in $, of $\"x\"$ $5 bills
\n" ); document.write( " $\"20%2A%28x%2B4%29=+value%2C+in+%24%2C+of+%7B%7B%7Bx%2B4\"$ $20 bills
\n" ); document.write( "So, our equation is
\n" ); document.write( " $\"5%2Ax%2B20%2A%28x%2B4%29=880\"$
\n" ); document.write( "
\n" ); document.write( "Solving:
\n" ); document.write( " $\"5%2Ax%2B20%2A%28x%2B4%29=880\"$
\n" ); document.write( " $\"5x%2B20x%2B20%2A4=880\"$
\n" ); document.write( " $\"25x%2B80=880\"$
\n" ); document.write( " $\"25x=880-80\"$
\n" ); document.write( " $\"25x=800\"$
\n" ); document.write( " $\"x=800%2F25\"$
\n" ); document.write( " $\"x=32\"$
\n" ); document.write( " $\"x%2B4=32%2B4%29\"$
\n" ); document.write( " $\"x%2B4=highlight%2836%29\"$
\n" ); document.write( "Katie has $\"highlight%2836%29\"$ $20 bills. \n" ); document.write( "
