A company is planning to produce and sell a new line of computers. The fixed cost will be $320,000 and it will cost $600 to produce each computer. Each computer will be sold for $800.

1. Write the cost function, C, of producing "x" computers.

Cost=320,000+600x

To write the cost function, C, of producing "x" computers, we need to consider both the fixed cost and the variable cost.

The fixed cost is given as $320,000, which remains constant regardless of the number of computers produced. So, the fixed cost can be represented as 320,000.

The variable cost is the cost of producing each computer, which is $600 per computer. Since the total cost increases with the number of computers produced, we need to multiply the variable cost by the number of computers, "x". Therefore, the variable cost can be represented as 600x.

To find the total cost function, we sum up the fixed cost and the variable cost:

C(x) = 320,000 + 600x

Therefore, the cost function, C, of producing "x" computers is C(x) = 320,000 + 600x.
