Answer:
first and second, which are the same number line
Explanation:
250x + 300 ≥ 1,550 ( subtract 300 from both sides )
250x ≥ 1,250 ( divide both sides by 250 )
x ≥ 5
since x is greater than or equal to the number line will have a solid circle at 5, indicating x can be equal to 5.
the arrow will point to the right, indicating the values x can be greater than 5.
