(Source adapted from: http://www.intracen.org/exporters/organic-products/country-focus/Country-Profile-South-Korea/) With reference to the data above and your knowledge of economics, assess whether the price elasticity of supply (PES) is likely to be more price elastic for cars than for organic strawberries. (9) 5.9 McAfee is a US-based global computer software security company. In 2017, its revenue was over $2.5bn. The company operates a ‘fundraising match program. This means when one of its 7,600 employees participates in a fundraising activity, such as a walk, run or cycle event, the company will contribute an equal amount.
