But you can get good mental exercise solving the problem informally, using logical reasoning and mental arithmetic. \n" ); document.write( "The number of nickels is 3 more than the number of dimes, and the total value is $3.60. \n" ); document.write( "Set aside those 3 \"extra\" nickels, worth $0.15, leaving a value of $3.45 for the remaining coins. \n" ); document.write( "Those remaining coins are equal numbers of nickels and dimes. The value of one nickel and one dime is $0.15. $3.45/$0.15 = 23, so the remaining coins are 23 nickels and 23 dimes. \n" ); document.write( "Now add back in the other 3 nickels, making 26 nickels and 23 dimes. \n" ); document.write( "ANSWER: 26 nickels and 23 dimes \n" ); document.write( " \n" ); document.write( " |
