<PRE><B>Question 1013341</B>
6D+14P=136.50; drinks are D, popcorn is P
7D+2P=41
====
6D+14P=136.50
-49D-14P=-287,multiplying the second by -7
-43D=-150.50, add the two together.
Drinks are $3.50
substitute into second equation
$24.50+2P=41
2P=16.50
P=8.25
=============
Check with first equation
21+115.50=136.50
Drinks are $3.50
Popcorn is $8.50</PRE>
