Question

Alfalfa plant can take up metals from the ground and store them in their roots and stems. In 2002, a scientist claimed that an alfalfa plant could produce 20% of its weight in gold by taking up tiny gold particles left behind from rock mining. How many pounds of gold could be produced from 3000 ponds of alfalfa plants?

Short answer

The quantity of gold could be produced is 600 pounds.

Step-by-step solution

Step 1. Given Information.

The alfalfa plant can produce 20% gold of its weight and the weight is 3000 pounds.

Step 2. Calculation.

From 3000 pounds alfalfa plant can produced gold (in percent) $=20\%$

From 3000 pounds alfalfa plant can produced gold (in number) $\begin{array}{l}=\frac{20}{100}\cdot 3000\\ =\frac{60000}{100}\left[multiply\right]\\ =600\left[divide\right]\end{array}$

Step 3. Conclusion.

The quantity of gold could be produced is 600 pounds.
