Andrea's fish tank holds 30 gallons of water. Andrea estimates that every inch of a fish's length requires a gallon of water. She wants to purchase some corydoras that are 2 inches long, angelfish that are 5 inches long, and fancy guppies that are 3 inches long. Write an equation for the situation.

    Is there a question... like "can the water fit in the tank?" ?

    Ok, I think you're good... not too sure about = sign. I would assume it would be a =< sign because as long as the amount of water is =< 30, they can fit in the tank.
