Question

Does anyone know what the inequality would be?

Answer 1

Let x = number of batches.

So for every batch, you need 2 cups of flour, and you have 20 cups of flour. You cannot make a batch if you don't have the sufficient amount. So using our information, our inequality is $2x \leq 20$ . However, this can be further simplified.

For this inequality, divide both sides by 2, and your inequality is $x\leq 10$. In context, you can make up to 10 batches of cookies.
