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.

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