Answer:
A. 
In 4231, the value of the digit 3 is 110 less than the value of the digit 3 in 3421.
Step-by-step explanation:
We can see that the value of 3 In 4231 is in ten while the value of 3 in 3421 is in thousands.
So to get the actual division factor, let's take 3300 and divide it by 30, 
3300/30 = 110
So it's clear already, that the value of 3 in 4231 is 110 times less to the value in 3421

To factor first multily 100 and 1 and get 100
then find what 2 numbers multiply to get 100 and add to get 20
the numbers are 10 and 10
so 
split the center term up
100x^2+10x+10x+1
group
(100x^2+10x)+(10x+1)
undistribute
(10x)(10x+1)+(1)(10x+1)
undistribute/reverse distributive property
(10x+1)(10x+1)
(10x+1)^2
        
                    
             
        
        
        
Answer:
- 320 +0.05s ≥ 600
- sales ≥ $5600
Step-by-step explanation:
For sales of 's', Alan's earnings will be ...
   320 +0.05s
He wants that to be at least 600, so the inequality is ...
   320 +0.05s ≥ 600
__
Its solution is found by subtracting 320 and dividing by 0.05.
   0.05s ≥ 280
   s ≥ 5600
Alan's weekly sales must be at least $5600 for his earnings to cover his expenses.
