Answer 2

Calculation:

To calculate the amount of fresh chamomile flowers needed to obtain 78 kg of dried flowers, we need to consider that the chamomile loses 74% of its weight during the drying process.

Let's assume that the weight of fresh chamomile flowers needed to obtain 78 kg of dried flowers is x kg.

According to the given information, the chamomile loses 74% of its weight during drying. This means that after drying, the chamomile will weigh 26% of its original weight.

We can set up the following equation to solve for x:

x * 0.26 = 78

Simplifying the equation:

0.26x = 78

Dividing both sides of the equation by 0.26:

x = 78 / 0.26

Calculating the value of x:

x ≈ 300 kg

Therefore, approximately 300 kg of fresh chamomile flowers are needed to obtain 78 kg of dried flowers.

Answer:

To obtain 78 kg of dried chamomile flowers, approximately 300 kg of fresh chamomile flowers need to be collected.

Please note that the calculation is based on the assumption that the chamomile loses 74% of its weight during the drying process.
