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.
Combining those like terms would end as 3n.
Explanation: The end of a subtraction equation is basically just the negative number, except you add it to the other part.
For example, 2n is really -2n, and you just add -2n to 5n (which is positive,) and you get 3n.
