gigi has 200 coins of different values. the ratio of the number of 50-cent coins to the number of 20- cent coins to the number of 10-cent coins is 5:3:2. what is the total value of the 50- cent coins?
------------
5:3:2 is the same as 5x:3x:2x where
5x is # of 50-cent coins
3x is # of 20-cent coins
2x is # of 10-cent coins
-------------
EQUATION:
5x + 3x + 2x = 200
10x = 200
x = 20
5x = 100 (# of 50-cent coins)
3x = 60 (# of 20-cent coins)
2x = 40 (# of 10-cent coins)
