Solution

To calculate the percentage change in real GDP from 2020 to 2021, we first need to calculate the real GDP for each year. Real GDP is calculated by multiplying the quantity of each good by its price and then summing up these values for all goods.

For 2020: Ice cream cones: 2.501,000=2.50 * 1,000 = 2,500 Hot dogs: 1.25500=1.25 * 500 = 625 Surfboards: 100.0010=100.00 * 10 = 1,000 So, real GDP for 2020 = 2,500+2,500 + 625 + 1,000=1,000 = 4,125

For 2021: Ice cream cones: 3.50800=3.50 * 800 = 2,800 Hot dogs: 2.25400=2.25 * 400 = 900 Surfboards: 100.0014=100.00 * 14 = 1,400 So, real GDP for 2021 = 2,800+2,800 + 900 + 1,400=1,400 = 5,100

Now, we can calculate the percentage change in real GDP from 2020 to 2021 using the formula:

Percentage change = [(Real GDP in 2021 - Real GDP in 2020) / Real GDP in 2020] * 100%

Percentage change = [(5,1005,100 - 4,125) / $4,125] * 100% = 23.64%

So, the percentage change in real GDP from 2020 to 2021 is 23.64%.
