Q: Suppose in Gadgetland, the price of an iPad increases from $$10 to 18 $$and the price of an iPhone increases from $$5 to 8$$, with the market basket consisting of 4 iPads and 4 iPhones. What is the inflation rate between Year 1 and Year 2 using the CPI formula?

$$\frac{(4 \times 18 + 4 \times 8) - (4 \times 10 + 4 \times 5)}{4 \times 10 + 4 \times 5} \times 100 = 73\%$$

Q: Which equation correctly represents the expected rate of inflation as shown in the provided formula image?

$$\pi_t^e = \left( \frac{P_{t+1}^e - P_t}{P_t} \right) \times 100$$

Q: If the nominal GDP in Year 2 is $$172 and the real GDP in Year 2 is 100$$, what is the GDP deflator for Year 2?

$$\frac{172}{100} \times 100 = 172$$

Q: If the price level in Year 1 is 100 and in Year 2 is 172, what is the inflation rate between the two years?

$$\frac{172 - 100}{100} \times 100 = 72\%$$
