Algebra.Com's Answer #733765 by greenestamps(13203) You can put this solution on YOUR website! \n" ); document.write( "Without algebra, using logical analysis.... \n" ); document.write( "(1) Take away the \"extra\" 6 nickels, so that the remaining coins are equal numbers of nickels and dimes. The amount left is $5.55 - 6($.05) = $5.55-$.30 = $5.25. \n" ); document.write( "(2) Pair the remaining coins up into groups of 1 nickel and 1 dime. Each of those groups has a value of $0.15. \n" ); document.write( "(3) The number of those groups required to make the total of $5.25 is $5.25/$0.15 = 35. So there are 35 nickels and 35 dimes. \n" ); document.write( "(4) Bring back the \"extra\" 6 nickels, giving you the final answer of 41 nickels nd 35 dimes. \n" ); document.write( "Of course, if an algebraic solution is required, then the solution from the other tutor is fine. \n" ); document.write( " |
