    Answer: 300cal ≤ y ≤ 1200 cal

    Step-by-step explanation:

    Let’s define x as the number of cookies that you eat, and y as the number of calories you consume in those cookies.

    “if you eat no fewer than 2 cookies…”

    This is written as:

    2 ≤ x

    This means that x can be equal to 2, or larger than 2.

    “…and no more than 8 cookies”

    This is written as:

    x ≤ 8

    This means that x can be smaller than 8 or equal to 8.

    If we combine those two, we have:

    2 ≤ x ≤ 8

    And we know that each cookie contains 150 calories, and rememer that these numbers represent number of cookies, then the numbers of calories will be:

    2*150 cal  ≤ y ≤ 8*150 cal

    300cal ≤ y ≤ 1200 cal.
