When Jai emptied her piggy bank, there were nickels, dimes, and quarters. There were 2 times as many dimes as nickels, and 10 more quarters than nickels. If the total amount of money was 7.50, how many coins did she have?
\n" ); document.write( "
Let number of nickels be N
\n" ); document.write( "Then number of dimes = 2N
\n" ); document.write( "Number of quarters: N + 10
\n" ); document.write( "We then get the following VALUE equation: .05N + .1(2N) + .25(N + 10) = 7.5
\n" ); document.write( ".05N + .2N + .25N + 2.5 = 7.5
\n" ); document.write( ".5N = 7.5 - 2.5
\n" ); document.write( ".5N = 5
\n" ); document.write( "N, or number of nickels = \"highlight_green%28matrix%281%2C3%2C+5%2F.5%2C+or%2C+10%29%29\"
\n" ); document.write( "Number of dimes: \"highlight_green%28matrix%281%2C3%2C+2%2810%29%2C+or%2C+20%29%29\"
\n" ); document.write( "Number of quarters: \"highlight_green%28matrix%281%2C3%2C+10+%2B+10%2C+or%2C+20%29%29\"
\n" ); document.write( "She had a total of:
\n" ); document.write( "It is that simple....nothing CONFUSING and COMPLEX! \n" ); document.write( "
\n" );
