Part 1
​(a) Write a formula that gives the cost C of producing x compact discs. Be sure to include the fixed cost.

The formula that gives the cost C of producing x compact discs is:

C = $1.75x + $2800

The formula for the cost C of producing x compact discs is:

C = 1.75x + 2800

To calculate the cost (C) of producing x compact discs, we need to take into account the variable cost per disc and the fixed cost.

The variable cost per disc is given as $1.75. This means that for each disc produced, it costs $1.75.

The fixed cost is given as $2800. This is a one-time cost that remains constant regardless of the number of discs produced.

To calculate the cost of producing x compact discs, we use the following formula:

C = (variable cost per disc * x) + fixed cost

Substituting the given values:

C = ($1.75 * x) + $2800

So the formula for the cost C of producing x compact discs is:

C = $1.75x + $2800
