Answer:
$677.18 
Step-by-step explanation:
Data provided in the question:
Bill’s nominal income in 1990 = $1,009 per month
CPI value in the year 1990 = 149
CPI value in the year 2017 = 192
Now,
The Consumer price index ( CPI ) is given as :
CPI =  
thus,
for the given case of year 1990
149 =  
or
Real income in 1990 =  
or
Real income in 1990 = $677.18 
 
        
             
        
        
        
When it says x and y are directly related it means that x is multiplied by something to get y. To solve you divide y by x which is 840 divided by 6. Which is 140 then you multiply and solve so the y value for 5 is 700. The x value for 420 is 3 and the y value for 4 is 560.

The numbers are 5 and 12.
Smaller number = x
Larger number = y
x +y =17
y = 3x - 3
x +3x -3 = 17
4x = 20
x = 5
smaller number is 5
y = 3(5) - 3
y = 12
larger number is 12.
