So you can eliminate option 1.
Then you know that she bought, in total, 280 tropical fish. This means that all the tiggerfish and parrotfish together must sum 280:
x + y = 280.
The only option, between the remaining, with this equation is option 2.
So, option 2 is the correct.
A fixed value. In Algebra, a constant is a number on its own, or sometimes a letter such as a, b or c to stand for a fixed number. Example: in "x + 5 = 9", 5 and 9 are constants.
