document.write( "Question 166428: A stamp collection consist of 3,8, and 15 cent stamps. The number of 8 cent stamps is one less than triple the number of 3 cent stamps. The number of 15 cent stamps is six less than the number of 8 cent stamps. The total value of all the stamps is $2.47. Find the number of 8 cent stamps in the collection. \n" ); document.write( "

3 cent stamps =t
\n" ); document.write( "8 cent stamps =e
\n" ); document.write( "15 cent stamps =f
\n" ); document.write( "e=3t-1
\n" ); document.write( "f=e-8 f=(3t-1-8)=3t-9
\n" ); document.write( "t+e+f=2.47\r
\n" ); document.write( "\n" ); document.write( "substitute:e's value and f's value first 2 equations \"t%2B%283t-1%29%2B%283t-9%29=247\"\r
\n" ); document.write( "\n" ); document.write( "\"7t-10=247\" \"7t=257\" \"t=36.7\" \r
\n" ); document.write( "\n" ); document.write( "which isnt right since you need an integer
\n" ); document.write( "my guess is that should be 259 meaning t+e+f should have been equal to $2.49
\n" ); document.write( "so based on a final figure of \"7t=2.59\" \"t=37\"\r
\n" ); document.write( "\n" ); document.write( "if t=37 then e=3(37)-1=110 and f=110-8=102\r
\n" ); document.write( "\n" ); document.write( "3cent stamps =37
\n" ); document.write( "8cent stamps =110
\n" ); document.write( "15cent stamps =102\r
\n" ); document.write( "\n" ); document.write( "this again is based on the amount total of the stamps equaling $2.49
\n" ); document.write( "
\n" );
