Question 785011
p for pans
t for trays


Account for feeding people:
14p+6t=64 ----------check how the units work for each term to see how this makes sense.  Divide left and right by 2, gives,,,
{{{7p+3t=32}}}


Account for the money:
39p+12t=150 ----------again, if unsure, check how the units work.
Simplify this one by division by 3, rendering 
{{{13p+4t=50}}}


Solve the two simultaneous equations anyway you want.




{{{-(28p+12t)=-(128)}}}
{{{39p+12t=150}}}
----------------
{{{11p=22}}}
p=2 then t=?
