Answer:
We need to start with 5 kg of mushrooms
Step-by-step explanation:
The total of the dried mushrooms = mushrooms * percentage of weight kept
percentage of weight kept = 1- 80% = 20 %

1 kg = mushrooms * 20%
1 kg = mushrooms * .2
Divide each side by .2
1 /.2 = mushroom *.2 /.2
5 kg = mushrooms
We need to start with 5 kg of mushrooms

k=1/12
so y=1/12*x
when x=8, y=1/12*8=2/3
