To solve this answer, you are trying to find 55% of 600, because that is the number of people who chose plastic bag.
55% can be re-written as 55/100 OR 0.55 since percentages are always out of 100.
So, we do 0.55*600, which gives us 330. 330 people carry plastic bags.
It is proportional. They are all multiplied by three. (9*3=27)
Let y = f(x) = x^2 - 81
y + 81 = x^2
x = sqrt(y + 81)
switch y to x, x to y
y = sqrt(x + 81) = f-1(x)
