Answer: There are 12 bills for $20, 13 bills for $10 and 14 bills for $5.
Step-by-step explanation:
Let the number of twenties be x
Let the number of tens be x+1
Let the number of fives be x+2
Amount from twenties will be given as
![20\times x=20x](https://tex.z-dn.net/?f=20%5Ctimes%20x%3D20x)
Amount from tens will be given as
![10\times (x+1)=10x+10](https://tex.z-dn.net/?f=10%5Ctimes%20%28x%2B1%29%3D10x%2B10)
Amount from fives will be given as
![5\times (x+2)=5x+10](https://tex.z-dn.net/?f=5%5Ctimes%20%28x%2B2%29%3D5x%2B10)
According to question,
![20x+10x+10+5x+10=440\\\\35x+20=440\\\\35x=440-20\\\\35x=420\\\\x=\frac{420}{35}\\\\x=12](https://tex.z-dn.net/?f=20x%2B10x%2B10%2B5x%2B10%3D440%5C%5C%5C%5C35x%2B20%3D440%5C%5C%5C%5C35x%3D440-20%5C%5C%5C%5C35x%3D420%5C%5C%5C%5Cx%3D%5Cfrac%7B420%7D%7B35%7D%5C%5C%5C%5Cx%3D12)
So, there are 12 bills for $20, 13 bills for $10 and 14 bills for $5.
