Walter is helping to make cookies for a basketball tournament. He's made 15 cookies so far. His coach asked him to make at least 20 cookies but no more than 55.

Solve the inequality and interpret the solution. 20 ≤ x + 15 ≤ 55 5 ≤ x ≤ 40;

Walter needs to make at least 5 more cookies but no more than 40. 5 ≥ x ≥ 40;

Walter needs to make less than 5 more cookies or more than 40. 35 ≤ x ≤ 70;

Walter needs to make at least 35 more cookies but no more than 70. 35 ≥ x ≥ 70;

Walter needs to make less than 35 more cookies or more than 70.

Answer:

Option A.

5 ≤ x ≤ 40. Walter needs to make at least 5 more cookies but no more than 40.

Explanation:

Number of cookies walter cooked so far = 15

Assume that he needs to cook "x" more cookies, so total number of cookies he would cook will be (x + 15)

His coach asked him to make at least 20 cookies but no more than 55. We can represent this by:

20 ≤ Cookies to Cook ≤ 55

20 ≤ x + 15 ≤ 55

Subtracting 15, from both sides, we get:

5 ≤ x ≤ 40

This means, x can be atleats 5 and atmost 40. Since x represents the number of cookes hank will cook, the correct answer will be Option A:

5 ≤ x ≤ 40. Walter needs to make at least 5 more cookies but no more than 40.
