Try it on paper first. A hint, the key idea and the worked solution are here when you need them.

A company sells 500500500 kg of a medicine that it makes from a plant that a community has used for generations. The price is 404040 money units for each kilogram. By agreement, 10%10\%10% of the income goes to the community.

Biopiracy is the use of bio-resources by multinational companies and other organisations without proper authorisation from the countries and people concerned, and without compensatory payment. Developing countries are rich in biodiversity and traditional knowledge. In 1997 an American company obtained a patent on a basmati rice that was derived from varieties of Indian farmers. Neem and turmeric are other examples of attempts to patent uses, products and processes based on plants that are used by farmers and communities.

The worked solution

Have you tried it?

Work it out on paper first. It is fine to get stuck or make a mistake: that is how we learn. When you are ready, go through the solution one step at a time, and check each step against your own.

Given. 500500500 kg, 404040 money units per kilogram, a share of 10%10\%10%.

Plan. Find the income, take the share, and then reverse the sum for part (c).

Step 1. Income. 500×40=20 000500 \times 40 = 20\,000500×40=20000 money units.

Step 2. The community. 10100×20 000=2000\dfrac{10}{100} \times 20\,000 = 200010010​×20000=2000 money units.

Step 3. The share for 500050005000. 500020 000×100=25%\dfrac{5000}{20\,000} \times 100 = 25\%200005000​×100=25%.

Answer: 20 00020\,00020000 money units; 200020002000 money units; 25%25\%25%.

Check. The company keeps 20 000−2000=18 00020\,000 - 2000 = 18\,00020000−2000=18000 money units. A share of 25%25\%25% of 20 00020\,00020000 is 500050005000.
