Question

The cost y , in dollars, for a manufacturer to make x rings is represented by the line shown. The line slants gradually up from left to right. The line passes through the following points: (0 comma 100) (60 comma 175) (100 comma 225) What is the cost, in dollars, for the manufacturer to make 60 rings?

Accepted Answer

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.
