can you help me solve?

Bark Co$.$ manufactures dog toys. The costs per unit, for $20,000$ fog toys, are as follows:

Direct labor: $$6$ units cost

Direct materials: $$5$ units cost

Fixed overhead: $$2$ units cost

Variable cost: $$1$ units cost

Woof Inc. has offered to sell $20,000$ dog toys to Bark Co$.$ for $$14$ per dog toy. If Bark Co$.$ accepts Woof Inc.$\text{'}$s offer, she facilities used to manufacture dog toys could be used to produce cat toys. Revenues fi

sale of cat foys are estimated at $$50,000,$ with variable costs amounting to $50\%$ of sales. In addition, $$1$ per unit of the flxed overhead associated with the manufacture of dog toys could be eliminated.

What is the dollar difference between making and buying the dog toys?
