To calculate the Real GDP for 1989 using 1988 as the base year, we need to use the prices from 1988 and multiply them by the quantities produced in 1989.
Here's a breakdown:
-
Milk:
- Quantity in 1989 = 15
- Price in 1988 = $1.00
- Real GDP from Milk = 15 * $1.00 = $15
-
Butter:
- Quantity in 1989 = 20
- Price in 1988 = $0.50
- Real GDP from Butter = 20 * $0.50 = $10
-
Eggs:
- Quantity in 1989 = 4
- Price in 1988 = $0.25
- Real GDP from Eggs = 4 * $0.25 = $1
Now, we sum these values to get the Real GDP for 1989:
\[ \text{Real GDP} = \text{GDP from Milk} + \text{GDP from Butter} + \text{GDP from Eggs} \] \[ \text{Real GDP} = 15 + 10 + 1 = 26 \]
Therefore, the Real GDP in 1989 is $26.
