Algebra.Com's Answer #181664 by richwmiller(17219)![]() ![]() You can put this solution on YOUR website! to begin with we don't know how many coins there are total. \n" ); document.write( "We also need to know the total values of the coins. \n" ); document.write( "you can't assume 100 coins \n" ); document.write( "50% doesn't mean 50 pennies \n" ); document.write( "let x= total number of coins \n" ); document.write( ".50x=p \n" ); document.write( "the remaining is also 50% \n" ); document.write( "but half of that is 25% \n" ); document.write( "so 25%are quarters \n" ); document.write( "are equally nickels , dimes and half dollars. \n" ); document.write( "let n=number of nickels \n" ); document.write( "n=d \n" ); document.write( "n=h\r \n" ); document.write( "\n" ); document.write( "So that 3n=.25x \n" ); document.write( "so far then we have \n" ); document.write( "x=p+q+n+d+h \n" ); document.write( "x/2=p \n" ); document.write( "x/4=q \n" ); document.write( "3n=.25x \n" ); document.write( "n+d+h=.25x \n" ); document.write( "3n=n+d+h \n" ); document.write( "x/2+x/4+3n=x \n" ); document.write( "x=12n \n" ); document.write( "I suspect we are missing some info such as a dollar amount for something.\r \n" ); document.write( "\n" ); document.write( "Plus we haven't actually been asked to solve for anything in particular.\r \n" ); document.write( " \n" ); document.write( " \n" ); document.write( " \n" ); document.write( "\n" ); document.write( " \n" ); document.write( " |
