Question

A principal used a total of 25 flags that were either blue or yellow for field day. The principal used 20 blue flags. How many yellow flags were used?

Accepted Answer

Choice A is correct. It's given that a principal used a total of 25 blue flags and yellow flags. It's also given that of the 25 flags used, 20 flags were blue. Subtracting the number of blue flags used from the total number of flags used results in the number of yellow flags used. It follows that the number of yellow flags used is 25 - 20 , or 5 . Choice B is incorrect. This is the number of blue flags used. Choice C is incorrect. This is the total number of flags used. Choice D is incorrect and may result from conceptual or calculation errors.
