Explanation:

Gross domestic product is the total sum of final goods and services produced in an economy within a given period which is usually a year

GDP calculated using the expenditure approach = Consumption spending by households + Investment spending by businesses + Government spending + Net export

Consumption spending includes spending by households on goods and services. Consumption spending includes :  

spending on durables - e.g. buying a laptop  

spending on nondurables - e.g. buying clothes, food

spending on services  - e.g. payment of hospital bill  

the purchase of a textbook by a student is an example of consumption spending on durable goods

Investment - It includes purchases of goods and services made by businesses in the production of goods and services

Government spending - It includes government consumption expenditure and gross investment.  The purchase of a new  limousine for the president is an example of consumption expenditure

Net export = export  - import

the purchase of hotdog constitutes consumption of non durable goods and this would increase US GDP by $25
