Question

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.

Answer 1

Answer:

$5\leq x\leq 40$

Here, $x$ denotes the additional cookies that need to be made by Walter besides 15 cookies made by him so far

Step-by-step explanation:

Number of cookies made by Walter so far = 15

He is asked by his coach to make at least 20 cookies but no more than 55.

Let $x$ denotes the additional cookies that need to be made by Walter besides 15 cookies made by him so far.

The inequality is $20\leq x+15\leq 55$

Now solve this inequality.

$20\leq x+15\leq 55\\20-15\leq x\leq 55-15\\5\leq x\leq 40$
