D + 146 need to equal 180
e + 125 need to equal 180
d = 180 - 146 = 34
e = 180 - 125 = 55
Set up a proportion
3 coins:8 notes and then the other one 24 coins : x (unknown notes)
they have a relationship so we can set them equal to each other.
3/8=24/x cross multiply: 8 * 24 = 192
Now divide that by 3: 192/3 = 64
So there are 64 notes in the bag
