x = number of weeks
\n" ); document.write( "y = dollars saved
\n" ); document.write( "---
\n" ); document.write( "bryce:
\n" ); document.write( "y = 20x + 10
\n" ); document.write( "---
\n" ); document.write( "ethan:
\n" ); document.write( "y = 10x + 80
\n" ); document.write( "---
\n" ); document.write( "equal account balances:
\n" ); document.write( "20x + 10 = 10x + 80
\n" ); document.write( "10x = 70
\n" ); document.write( "x = 7
\n" ); document.write( "---
\n" ); document.write( "answer
\n" ); document.write( "at 7 weeks both will have $150 saved
