so I opened 8 treasure boxes and each had a number of coins in it the box with fewest was 503 coins while the box with the highest was 696 .So that means it must be a number between 4024 and 5568. what was the total number of coins I found?

White shapes and black shapes are used in a game. some of the shapes are circles. while the rest are squares. the ratio of the number of white shapes to the number of black shapes is 5: 11. the ratio of the number of white cicrles to the number of white squares is 3: 7. the ratio of the number of black circles to the number of black squres is 3: 8. work out what fraction of all the shapes are circles.
