No units of measure are given, so I could say
P and Q have units of ounces, grams, or whatever.
I could even make up units
-----------------------------
I'll say there are ounces of so there
must be ounces of Q
( this is a ratio of 1:4.5 )
------------------------------
For P:
ounces silver
ounces aluminum
For Q:
ounces silver
ounces copper
ounces aluminum
-------------------------------------
ounces silver
ounces aluminum
ounces copper
---------------------------------------
The total weight of P + Q is
ounces
----------------------------
For silver:
33% silver
For copper:
29% copper
----------------------
check answers:
For aluminum:
39%
this looks close enough
Hop I got it!
