Answer:
$15 trillions
Step-by-step explanation:
The computation of the GDP is shown below:
GDP = Consumption + Investment + Government purchase + Net exports
where,
Consumption = $10 trillions
Investment = $2.5 trillions
Government purchase = $3 trillions
Net exports = Exports - imports
= $1 trillion - $1.5 trillion
= -$0.5 trillion
So, the GDP would be
= $10 trillions + $2.5 trillions + $3 trillions - $0.5 trillions
= $15 trillions
= 13.5 trillions
