Algebra.Com's Answer #753049 by greenestamps(13200)![]() ![]() You can put this solution on YOUR website! \n" ); document.write( "Informally.... \n" ); document.write( "(1) Count the \"extra\" 4 dimes and set them aside. The remaining coins are equal numbers of nickels and dimes, with a total value of $1.75-$0.40 = $1.35. \n" ); document.write( "(2) Group the remaining coins in groups of one nickel and one dime each. The value of each group is $0.15. \n" ); document.write( "(3) The number of groups worth $0.15 each needed to make the remaining $1.35 is 1.35/0.15 = 135/15 = 9; so there are 9 nickels and 9 dimes. \n" ); document.write( "(4) Now bring back in those 4 dimes you set aside at the beginning, to find that the number of nickels in his pocket is 9 and the number of dimes is 13. \n" ); document.write( " |
