Q: Suppose the working-age population is 250 million, the labor force is 160 million, and 150 million people are employed. What is the unemployment rate? $$\text{Unemployment Rate} = \frac{\text{Number of Unemployed}}{\text{Labor Force}} \times 100$$

$$\frac{10}{160} \times 100 = 6.25\%$$

Q: If the Consumer Price Index (CPI) was 120 in 2020 and 126 in 2021, what was the inflation rate between these years? $$\text{Inflation Rate} = \frac{\text{CPI}_{2021} - \text{CPI}_{2020}}{\text{CPI}_{2020}} \times 100$$

$$\frac{126 - 120}{120} \times 100 = 5\%$$
