Answer:
GDP is $ 850,000,000.00
Step-by-step explanation:
GDP is an acronym for Gross Domestic Product which represents the value of goods and services in an economy over a period of time,usually a year.
As a result, GDP in this economy can be computed thus:
GDP=quantity of speedboats*selling price of speedboat+quantity of race cars*selling price of race car
GDP=(10,000*$40,000)+(5000*$90000)
GDP=$ 400,000,000.00+$450,000,000.00
GDP=$ 850,000,000.00
The price of the engines at $9000 and $12,000 are relevant anymore as they are already considered in the total price of speedboat and race car.
