Percentage increases and decreases, are found by setting the problem up proportionally.
You are trying to find what percentage of 17.37 is 8.30 first.
so What %/100 = 8.30/17.37
Now define a variable:
Let x = What%
x/100 = 8.30/17.37
17.37x = 830
x = 830/17.37
x ≈ 47.78
8.30 is approximately 47.78% of 17.37, so the percentage decrease is 100% - 47.78% = 52.22%
The percentage decrease is approximately 52.22%

Hello!
First we have to find out how much each copy cost
240 / 60 = 4
Since each magazine cost $4 the answer is y = 4x; (1,4), (2,8), (3,12)

6+9x=456
Subtract 6 from both sides
6-6+9x = 456-6
9x = 450
Divide each side by 9
X = 50
Plug it in 6+9(50) = 456
6+450 = 456
