a stamp collection consist of 5 (F NUMBERS SAY), 13(T), and 18(E) cent stamps. The number of 13 cent stamps is one less than twice the number of 5 cent stamps. the number of 18 cent stamps is five more than the number of 13 cent stamps. the total value of all the stamps is $2.60. find the number of 13 cent stamps in collection.
\n" ); document.write( "TWICE THE 5 C STAMPS=2F
\n" ); document.write( "ONE LESS=2F-1=T......2F=T+1.....F=(T+1)/2=0.5(T+1).............I
\n" ); document.write( "5 MORE THAN 13 C STAMPS =T+5=E.........................II
\n" ); document.write( "VALUE OF 5 C STAMPS=5F
