The remaining value is then $3.50; consisting of equal numbers of nickels and quarters, and twice that many dimes. \n" ); document.write( "(2) Consider the value of one nickel, one quarter, and two dimes; it is $0.50. \n" ); document.write( "(3) $3.50 is 7 times $0.50; so the $3.50 consists of 7 each of nickels and quarters, and twice that many dimes. \n" ); document.write( "So there are 14 dimes. \n" ); document.write( " |
