document.write( "Question 212084: Tanner has $4.35 in nickels and quarters. If he has 15 more nickels than quarters how many of each coin does he have?
\n" );
document.write( "Would it be 2x + 15= 4.35? Is that how I write the equation? Then how do I find both the amount of nickels and quarters? \n" );

Algebra.Com's Answer #160206 by Fombitz(32388)![]() ![]() You can put this solution on YOUR website! Let N be the number of nickels and Q the number of quarters. \n" ); document.write( "You will have two equations. \n" ); document.write( "The first relates the number of coins. \n" ); document.write( "\"he has 15 more nickels than quarters\" \n" ); document.write( "1. N=15+Q \n" ); document.write( "The second is the total value of the coins. \n" ); document.write( "Each nickel is worth 5 cents. \n" ); document.write( "Each quarter is worh 25 cents. \n" ); document.write( "The total is $4.35 or 435 cents. \n" ); document.write( "2. 5*N+25*Q=435. \n" ); document.write( "Now substitute the expression for N into eq. 2 and solve for Q. \n" ); document.write( "Then go back to eq. 1 and solve for N. \n" ); document.write( "Re-post or email if you get stuck or need more help. \n" ); document.write( "Good luck! \n" ); document.write( " \n" ); document.write( " |
