Sam saved $30 per week. ⇒ STORE OF VALUE
Sam pays $140 for the Blu-Ray player. ⇒ MEDIUM OF EXCHANGE
Explanation:
The four main functions of money are:
- it serves as a unit of account: it provides a common measure of the value of goods and services being exchanged.
- it serves as a store of value: money holds its value over time, so it serves as a store of value.
- it serves as a medium of exchange: you can use money to purchase goods and services
- it serves as a standard of deferred payment: money serves as a way of valuing a debt, so you can acquire goods now and pay for them later.
 
        
             
        
        
        
Answer:
Grew by 2% 
Explanation:
Given: nominal GDP =12% positive value cause it grew by 12% during these years.
               Population grew by 4%
               GDP deflator = 6% positive value cause it also grew by 6%
Question says we must find real GDP per person for the 4 year term that the president has served for so we will use the formula to calculate GDP Deflator to actually solve for Real GDP as we know the formula is GDP Deflator= (nominal GDP per person%)/(Real GDP per person%)x100
So we already have the nominal GDP and the GDP deflator therefore we substitute to the above formula:
6% = (12%)/ (Real GDP per person percentage) x100, and now we solve for Real GDP per person%
Therefore we multiply both sides with Real GDP percentage and get:
Real GDP per person %( 6%) = 12% and then we divide both sides with 6%,
Therefore Real GDP is 2% so we also see that real GDP has actual grown by 2% because the GDP deflator grew instead of decreasing where nominal GDP is also positive so if we have a fraction where an answer is positive we know both fraction values must be positive pus if the GDP deflator increases both nominal and Real GDP increase and that’s the relationship they have.
