Not being American, I assume a quarter is 25 cents and a dime is 10 cents. \n" ); document.write( "Let the number of quarters be x, and therefore the number of dimes is 22 - x \n" ); document.write( "So 25x + 10(22 - x) = 355 \n" ); document.write( "25x + 220 - 10x = 355 \n" ); document.write( "15x = 135 \n" ); document.write( "x = 9 \n" ); document.write( "so number of quarters is 9 and number of dimes is 13 \n" ); document.write( " |
