Answer:
Option a. Y=3x
Step-by-step explanation:
Let us use cross multiplication method.
Let the cost of 1 magazine be x.
No. of copies                               Cost
1)50                                                $150
2)1                                                      x
50x=150 x 1               equation(1)
x=150/50
x=$3
Now see equation (1),
150=50x
150=50 x 3
Here let us represent the cost as y and no. of copies as x.
Y=3x
Therefore, a. Y=3x is the right answer.
Thank you!
                                              
 
        
             
        
        
        
Let X describes the sales 
350.25+0.12x=800.5
Now solve for x
0.12x=800.5-350.25
0.12x=450.25
X=450.25÷0.12
X=3,752.08 
the sales necessary for the salesperson to earn at least $800.50 in one week is 3,752.08
        
             
        
        
        
Answer:

Step-by-step explanation:
Angle A and angle E are the same value, therefore you could replace angle E with angle A. So that would make a triangle with angle C, angle D, and angle A. Knowing the sum of all angles in a triangle is 180, we can make an equation representing this.

Now simply silve the equation to find x.

There is your answer.
 
        
             
        
        
        
The amount after 2 years is $2,295.
Given that, 
- The invested amount is $1,240.
- The rate of interest is 8%.
- The number of years is 2 × 4 = 8
Based on the above information, the amount after 2 years is 
Future value = Present value ×(1 + rate of interest)^number of years 
= $1,240 × (1 + 0.08)^8
= $1,240 × 1.08^8
= $2,295
Therefore we can conclude that the amount after 2 years is $2,295.
