Explanation: First, the circle is filled, meaning the inequality will include that number(must be greater/less than AND equal to). Next , plug in a number along the green line to see if it fits. Remember that < means less than and > is greater than. By plugging in 70 for s, the answer would be s<_ 75 because 70 is smaller than 75. If you used the opposite sign (s>_75), this would be incorrect because 70 is NOT greater than 75. So, the answer is s<_ 75.
