    Answer: 3.00 ≥ 0.21 x

    The number of Comet Goldfish Eva can buy = 14.

    Step-by-step explanation:

    Let 'x' be the number of Comet Goldfish.

    The cost of each fish = $0.21

    Then, the cost of 'x' Comet Goldfish = $0.21 x

    Total amount Eva has = $3.00

    Now, the required inequality is

    Total amount Eva has ≥ Cost of 'x' Comet Goldfish

    3.00 ≥ 0.21 x

    To find x, we divide both sides by 0.21, we get

    14.2857142857 ≥x

    ⇒x = 14 [∵ x cannot be a decimal number as it represents the number of fish.]

    Hence, the number of Comet Goldfish Eva can buy = 14.
