3t=2*r
\n" ); document.write( "r=a+b+c
\n" ); document.write( "2*(a+b+c)=3t
\n" ); document.write( "coins
\n" ); document.write( "1,5,10,25,50,100
\n" ); document.write( "if Tom has three alike he has
\n" ); document.write( "3,15,30,75,150 or 300
\n" ); document.write( "so Rebecca has a total of 1.5, 7.5, 15, 27.5, 75 or 150
\n" ); document.write( "she can't have 1.5, 7.5, 27.5
\n" ); document.write( "so she must have
\n" ); document.write( "15, 75 or 150
\n" ); document.write( "she needs three different coins to add up to 15, 75 or 150
\n" ); document.write( "5 and 10 add up to 15 but are only two coins\r
\n" ); document.write( "\n" ); document.write( "same with 75 cents 25 and 50 add up to 75
\n" ); document.write( "and also with 150
\n" ); document.write( "there are no current coins in circulation that meet the requirements\r
