Answer:
2022
Step-by-step explanation:
2 + 4x = y
y = 2 + 4(505)
y = 2 + 2020
y = 2022
 
        
             
        
        
        
The fisherman caught 365kg During El Niño. You subtract 540kg by 85.
        
             
        
        
        
To find the total of what you sold for each package, you'll need to write two equations. Know that x = paper plate packages and y = utensil packages. 
First, x + y = 15 shows that there has to be fifteen packages, and 8x + 5y = 90 shows the $ made from selling a certain number of packages. 
Next, you can solve by substitution, so change x + y = 15 to y = 15 - x.
To find our x, substitute the y in 8x + 5y = 90 to get 
8x + 5(15 - x) = 90 
Distribute: 8x + 75 - 5x = 90
Combine the X's and subtract the 75: 3x = 15
Divide the 3: x = 5
Now with our x, we can put 5 into the original equation x + y = 15 to get 5 + y = 15. Subtracting the 5, we get y = 10. 
So, you have delivered 5 paper plate packages and 10 utensil packages.
