According to the midpoints formula, the price elasticity of demand between points A and B on the initial graph is approximately .
Suppose the price of bippitybops is currently $60 per bippitybop, shown as point A on the initial graph. Because the price elasticity of demand between
points A and B is
, a $20-per-bippitybop decrease in price will lead to

So, you can get 71 Afghanis for $1? How cool. Does that mean you can buy a lot of stuff in Afghanistan for only $1? How do you know that your purchasing power in Afghanistan is stronger than in the United States? Yes, with an exchange rate of 71 Afghan Afghani for 1 US dollar, you can buy many things in Afghanistan for just $1. However, purchasing power isn't solely determined by the exchange rate. It also depends on the cost of goods and services in each country. For example, if a meal in Afghanistan costs 200 Afghanis, you would need about $2.82 to buy that meal in US dollars (since 200 Afghanis divided by 71 Afghanis per dollar equals approximately $2.82). So, while the exchange rate allows you to get more Afghanis for your dollars, you also need to consider how much things cost in Afghanistan.
