Answer:
1x + 4y > 1,800
Explanation:
This is the correct answer because if you had put 1x + 4y < 1,800 that would be incorrect bc the inequality is saying that 1x + 4y is less than 1,800. Within this case that would be wrong bc they have to reach the goal of 1,800. It cannot be lower than 1,800 so therefore 1x + 4y > 1,800 represents the correct answer of the goal being reached.
