Answer:
d. nominal GDP is $500, real GDP is $400, and the GDP deflator is 125.
Explanation:
Real GDP is total output produced in an economy within a given period multiplied by base year prices 
Nominal GDP is the sum of all final goods and services produced in an economy within a given period multiplied by current year prices.
Nominal GDP = (100 × $3) + (50 × $4) = 
 $500
Real GDP = (100 × 1.5) + (50 × $5) = $400
GDP deflator = (nominal gdp / real gdp) x 100
(500 / 400) × 100 = 125

Answer:
The correct option is D,cannot be determined from the data provided
Explanation:
Break-even points in units=fixed costs/contribution margin per unit
Contribution margin per unit =selling price -variable cost
In other words, from the scenario, it is clear that the numerator fixed costs has increased and also a reduction in variable cost per unit implies an increase in contribution margin per unit since a lesser variable cost is being deducted from selling price.
The impact of both increases in fixed costs and contribution margin cannot be determined except if more details is provided which will give further guidance regarding which of the two increased at a higher rate compared to the other.
 
        
             
        
        
        
Answer:
Assuming that Samuel's retiring age is exactly 65 years old, and he starts collecting benefits 24 months before his full retirement age (exactly on his birthday number 63), then he will receive $867 per month (or 86.7% of his full benefits). 
This calculation varies depending on the number of months, e.g. 
months before full retirement age                   % of full retirement benefit
24                                                                    	86.7%
23                                                                      87.2%
22                                                                      87.8%
21                                                                      88.3%	
20                                                                      88.9%	
19                                                                      89.4%	
18                                                                      90.0%	
17                                                                      90.6%	
16                                                                      91.1%	
15                                                                      91.7%	
14                                                                      92.2%	
13                                                                      92.8%
