Eva is buying Comet Goldfish to add to her aquarium. Each fish costs $0.21, and Eva has $3.00. Which of these represent the inequality and/or solution for how many Comet Goldfish Eva can buy?

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.
