If 2000 is the base year, what is the real GDP in 2001?

See my post to "Urgent economics - GDP"

USE THE EXPENDITURE EQUATION FOR GDP TO FIND VALUES FOR EACH SECTOR FOR YEARS 1929 AND 1933

To find the change in quantity and price for each category from the year 2000 to the year 2001, you need to subtract the values of the year 2000 from the values of the year 2001.

For Popcorn:
The quantity of popcorn in 2000 is 200, and in 2001 it is 250.
Therefore, the change in quantity is 250 - 200 = 50.

The price of popcorn in 2000 is $1, and in 2001 it is $2.
Therefore, the change in price is $2 - $1 = $1.

For Novels:
The quantity of novels in 2000 is 50, and in 2001 it is 30.
Therefore, the change in quantity is 30 - 50 = -20.

The price of novels in 2000 is $20, and in 2001 it is $25.
Therefore, the change in price is $25 - $20 = $5.

For Shoes:
The quantity of shoes in 2000 is 8, and in 2001 it is 10.
Therefore, the change in quantity is 10 - 8 = 2.

The price of shoes in 2000 is $100, and in 2001 it is $80.
Therefore, the change in price is $80 - $100 = -$20.

Overall, we have the following changes:

Popcorn:
Change in quantity: +50 units
Change in price: +$1

Novels:
Change in quantity: -20 units
Change in price: +$5

Shoes:
Change in quantity: +2 units
Change in price: -$20
