Tom saves $20 more than Ryan each month.
At the end of a certain number of months, Tom saved $330 and
Ryan saved $130
The difference between this is $200
If T saves $20 more than R each month,
T will save $200 more than R in 200/20= 10mths
330 / 10 = 33 (amount Tom saves each month)
33+18= 51 (Tom's monthly money)
51-20= 31 (Ryan's month money)
So, Tom recieves 51 monthly and Ryan recieves 31 monthly :D
Hope i helped!
