When mushrooms are dried, they lose 80 percent of their mass. what weight of mushrooms must be picked to get 1 kg of dry mushrooms?

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 %

We want 1 kg of dried mushrooms.   Substitute in what we know

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
