Constraints are simply the subjects of an objective function.

The inequality that represents the constraint is: 12x + 6y \le 20

Represent the number of hats with x, and the number of scarves with y.

From the question, we have:

  • He spends 12 hours to knit a hat
  • He spends 6 hours to knit a scarf

So, the equation of the total time spent is:

Time = 12x + 6y

This time spent is not more than 20 hours.

So, the inequality is

12x + 6y \le 20

Hence, the inequality that represents the constraint is: 12x + 6y \le 20
