Q: If the Consumer Price Index (CPI) was 130.4 in 2017 and 133.8 in 2018, what was the rate of inflation between these years? Use the formula $$\frac{CPI_{2018} - CPI_{2017}}{CPI_{2017}} \times 100.$$

$$\frac{133.8 - 130.4}{130.4} \times 100 = 2.6\%$$

Q: If the unemployment rate is calculated as $$\frac{U}{E+U} \times 100$$, where $$U is $$the number of unemployed and $$E is $$the number of employed, what is the unemployment rate if $$U = 2$$ million and $$E = 18$$ million?

$$\frac{2}{20} \times 100 = 10\%$$
