a. $ \$ 6000 .$ b. $ \$ 8000 .$

Work Step by Step

The cost is given by the function: $C=4000+2x$ where $x$ is the number of watches and $C$ is the cost in dollars. Then we have: a. The cost of producing 1000 watches is $ C=4000+2(1000)=\$ 6000 .$ b. The cost of producing 2000 watches is $ C=4000+2(2000)=\$ 8000 .$
