The bowl contained 150 coins. if they were all pennies and nickels and their total value was $2.70, how many coins of each type were there?\r
\n" ); document.write( "\n" ); document.write( "Let p = penny and n = nickels
\n" ); document.write( "p + n = 150
\n" ); document.write( "p + 5n = 270 [pennies are 1cent and nickels are 5 cents]
\n" ); document.write( "Use the elimination method
\n" ); document.write( "Subtract equation two from equation one
\n" ); document.write( "-4n = -120
\n" ); document.write( "Divide both sides by -4
\n" ); document.write( "n = 30
\n" ); document.write( "If there are 30 nickels, there must be 120 pennies.\r
\n" ); document.write( "\n" ); document.write( "
\n" ); document.write( "
