To calculate the Real GDP for 1989 using 1988 as the base year, we need to use the quantities from 1989 but the prices from 1988.
Here's how to calculate it:
-
Milk:
- Quantity in 1989: 15
- Price in 1988: $1.00
- Total = 15 * $1.00 = $15
-
Butter:
- Quantity in 1989: 20
- Price in 1988: $0.50
- Total = 20 * $0.50 = $10
-
Eggs:
- Quantity in 1989: 4
- Price in 1988: $0.25
- Total = 4 * $0.25 = $1
Now, we sum the totals for all three products:
- Total Real GDP = $15 (Milk) + $10 (Butter) + $1 (Eggs)
- Total Real GDP = $26
So, the Real GDP in 1989, with 1988 as the base year, is $26.
