Answer 3

Calculation 1: How many dried mushrooms can be obtained from 35 kg of fresh mushrooms?

To calculate the amount of dried mushrooms that can be obtained from 35 kg of fresh mushrooms, we need to consider that the dried mushrooms make up 14% of the weight of the fresh mushrooms.

Step 1: Calculate the weight of the dried mushrooms: - 14% of 35 kg = 0.14 * 35 kg = 4.9 kg

Therefore, 35 kg of fresh mushrooms can yield approximately 4.9 kg of dried mushrooms.

Calculation 2: How many fresh mushrooms are needed to obtain 2.8 kg of dried mushrooms?

To calculate the amount of fresh mushrooms needed to obtain 2.8 kg of dried mushrooms, we need to consider that the dried mushrooms make up 14% of the weight of the fresh mushrooms.

Step 1: Calculate the weight of the fresh mushrooms: - Let x be the weight of the fresh mushrooms. - 14% of x = 2.8 kg

Step 2: Solve for x: - 0.14x = 2.8 kg - Divide both sides by 0.14: x = 2.8 kg / 0.14 = 20 kg

Therefore, approximately 20 kg of fresh mushrooms are needed to obtain 2.8 kg of dried mushrooms.
