let s = no. of coins Sammy has
\n" ); document.write( "\"Aly had 7 times as many 25-centavo coins as Sammy has.\"
\n" ); document.write( "therefore
\n" ); document.write( " 7s = no. of coins Aly has
\n" ); document.write( ":
\n" ); document.write( "sammy and ally had a total of 448 pieces of 25-centavo coins.
\n" ); document.write( " s + 7s = 448
\n" ); document.write( " 8s = 448
\n" ); document.write( " s = 56 coins Sammy has
\n" ); document.write( "and
\n" ); document.write( " a = 7*56
\n" ); document.write( " a = 392 coins Aly has
\n" ); document.write( ":
\n" ); document.write( " How many 25- centavo coins should Ally give to Sammy so that Sammy would have 3 time as many coins as Ally has?
\n" ); document.write( "Let c = no. of coins A gives S to accomplish this
\n" ); document.write( " 56 + c = 3(392 - c)
\n" ); document.write( " 56 + c = 1176 - 3c
\n" ); document.write( " c + 3c = 1176 - 56
\n" ); document.write( "4c = 1120
\n" ); document.write( "c = 1120/4
\n" ); document.write( "c = 280 coins A gives to S
\n" ); document.write( ":
\n" ); document.write( ":
\n" ); document.write( "Check this, find how many coins each has after this is done
\n" ); document.write( "56 + 280 = 336 coins
\n" ); document.write( "392 - 280 = 112 coins
\n" ); document.write( "3 * 112 = 336\r
