Answer by mukhopadhyay(490)   (Show Source):
You can put this solution on YOUR website! Let the number of gift wraps sold = x;
Total number of rolls sold = 480;
So, total number of print wraps sold = 480-x;
Cost of x gift wraps = 4x
Cost of (480-x) print wraps = 6(480-x);
On the other hand, total Cost of both rolles = 2340
Hence 4x + 6(480-x) = 2340
=> 4x + 2880 - 6x = 2340
=> 6x-4x = 2880-2340
=> 2x = 540
=> x = 270
Answer: Number of gift wraps sold was 270 and the number of print wraps sold was 210 (480-270)
