Algebra.Com's Answer #132122 by MathTherapy(10555) You can put this solution on YOUR website! Let the amount of quarters that she has be q \n" ); document.write( "Then the amount of dimes she has is q + 5 \n" ); document.write( "And, the amount of nickels she has is 2(q +5), or 2q + 10\r \n" ); document.write( "\n" ); document.write( "Algebraic expression: .25q + .1(q + 5) + .05(2q + 10) = 3.25 \n" ); document.write( " .25q + .1q + .5 + .1q + .5 = 3.25 \n" ); document.write( " .45q = 2.25 \n" ); document.write( " q = 5 \n" ); document.write( "She has 5 quarters – $1.25 \n" ); document.write( "She has 10 dimes – $1.00 \n" ); document.write( "She has 20 nickels - $1.00 \n" ); document.write( " \n" ); document.write( " |
