Explanation

Choice C is correct. The line shown represents the cost $y$ , in dollars, for a manufacturer to make $x$ rings. For the line shown, the x-axis represents the number of rings made by the manufacturer and the y-axis represents the cost, in dollars. Therefore, the cost, in dollars, for the manufacturer to make $60$ rings is represented by the y-coordinate of the point on the line that has an x-coordinate of $60$ . The point on the line with an x-coordinate of $60$ has a y-coordinate of $175$ . Therefore, the cost, in dollars, for the manufacturer to make $60$ rings is $175$ .

Choice A is incorrect and may result from conceptual or calculation errors.

Choice B is incorrect. This is the cost, in dollars, for the manufacturer to make $20$ rings.

Choice D is incorrect. This is the cost, in dollars, for the manufacturer to make $100$ rings.
