Henry counted the money he saved for one month and found he has $8990 consisting of $100, $50 and $20 bills. He had half as many $50 bills as $20 bills but2 times as many as $100 bills as $50 bills.
How many bills of each kind did he have?

.5x = 50 bills
2(.5x)= 100 bills
Is that right?
Then how do you solve it?

no he has half of as many $50 bills as $20
so
$ 50 bills are x/2

20x+(.5x)(50)+100x=8990
now solve for x
