Answer: $156
Explanation:
The gross domestic product is referred to as the value of the final goods which a particular country produces for that economy.
Based on the information given, the GDP will be calculated as:
GDP = C + I + G + X - M
where C = consumption = $120
I = Investment = $25
G = government purchases = $15
X = exports = $8
M = imports = $12
GDP = C + I + G + X - IM
GDP = $120 + $25 + $15 + $8 - $12
GDP = $156
