- - - - - -_win_tokens_that_are - - - ~ At a state fair, attendees can worth a different number of points depending on the shape. One attendee won S square tokens and C circle tokens worth a total of 1,120 points. The 80S+90C = 1,120 equation represents this situation. How many more points is a circle token worth than a square token?
Correct answer: D (parsed from the explanation — this source omits an answer key for this item)
Explanation
80 +90 =1,120 Choice D is correct. It’s given that the equation S C represents this situation, where S is the number of square tokens won, C is the number of 1,120 circle tokens won, and is the total number of points the tokens are worth. It 80 follows that S represents the total number of points the square tokens are 80 90 worth. Therefore, each square token is worth points. It also follows that C represents the total number of points the circle tokens are worth. Therefore, each 90 90 circle token is worth points. Since a circle token is worth points and a 80 90-80 10 square token is worth points, then a circle token is worth , or , more points than a square token. Choice A is incorrect and may result from conceptual or calculation errors. Choice B is incorrect. This is the number of points a circle token is worth. Choice C is incorrect. This is the number of points a square token is worth.
