A factory produces toys and has a maximum production capacity of 1,000 toys per day. If they produce dolls and action figures, and each doll takes 2 hours to make while each action figure takes 1 hour, write an inequality to represent the total production time available. How many dolls and action figures can they produce?

• The factory can produce up to 12 dolls and 0 action figures, or any combination of dolls and action figures that satisfies the inequalities 2x + y <= 24 and x + y <= 1000.

• The factory can produce 24 dolls and 12 action figures.

• The factory can produce 500 dolls and 500 action figures.

• The factory can produce 0 dolls and 1000 action figures.
