The 2 numbers are m and n.
m + n = 7.2
m - n = 2.7Add the 2 equations and get
2m = 7.2 + 2.7 = 9.9
m = 9.9/2 = ?
Once you find m, plug its value into ether equation and get n.
Answer:
Since the output of consumption is most likely waste it is hard to track where the waste is going. Whereas with production theory the output is the product which goes to the consumer. This is much more easy to observe and is therefore "directly observable."
