<h3><u>Question:</u></h3>
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.
<h3><u>Answer:</u></h3>
Walter needs to make at least 5 more cookies but no more than 40.
The inequality is 5 ≥ x ≥ 40
<h3><u>Solution:</u></h3>
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.
So we can represent the above sentence as:
20 ≤ Cookies to Cook ≤ 55
20 ≤ x + 15 ≤ 55
Subtracting 15, from both sides, we get:
5 ≤ x ≤ 40
So x can be less than or equal to 40 and x can be greater than or equal to 5
This means, x can be atleast 5 and atmost 40
Therefore Walter needs to make at least 5 more cookies but no more than 40.
