He would notice that the numbers are starting at two and increasing by 2 each time. Also, all the numbers are even.
The pattern is that you are simply counting by 2's.
2, 4, 6, 8, 10, 12, ....
Let x represent the amount of 10% solution used.
Let y represent the amount of 25% solution used.
Since 30 liters of 15% solution are being made, our first equation is
x + y = 30
Now we deal with the actual peroxide in each solution.
x liters of 10% peroxide contain 0.1x liters of peroxide.
y liters of 25% peroxide contain 0.25y liters of peroxide.
30 liters of 15% peroxide contain 0.15 * 30 = 4.5 liters of peroxide.
From this information, we can write our second equation.
0.1x + 0.25y = 4.5
We have a system of equations:
x + y = 30
0.1x + 0.25y = 4.5
Multiply the first equation by -0.25 and add to the second equation.
-0.25x - 0.25y = -7.5
0.1x + 0.25y = 4.5
---------------------------
-0.15x = -3
x = 20
Answer: 20 liters

1 125 900
2 525 300
B) Cost Table
1 2 3 Total
Component 1 1625 9000 10625
Component 2 7875 3600 11475
Total cost 7875 5225 9000 22100
Step-by-step explanation:
Table 1:
Supplier
Component 1 2 3
1 $12 $13 $10
2 $15 $12 $10
Table 2:
Supplier 1 2 3
Capacity 525 975 900
Now we are supposed to find production plan for the next period includes 1025 units of component 1 and 825 units of component 2
So,
Supplier
Component 1 2 3
1 125 900
2 525 300
Cost Table :
1 2 3
Component 1 
Component 2 
Cost Table
1 2 3 Total
Component 1 1625 9000 10625
Component 2 7875 3600 11475
