Sam earn 300 more than bob
Sam save 4900
Bob save 2800
Since sam earn more by 300
And they spend the same
4900 -2800 = 2100
This is the difference btw their saving
Using 2100 we can find out how long they save
2100÷3 =7
They save for 7 years
2800 ÷7= 400
So bob save 400 a month
Since they both spend 1500
1500 + 400 =1900
Bob earn $1900 a month
Sam save 4900
Bob save 2800
Since sam earn more by 300
And they spend the same
4900 -2800 = 2100
This is the difference btw their saving
Using 2100 we can find out how long they save
2100÷3 =7
They save for 7 years
2800 ÷7= 400
So bob save 400 a month
Since they both spend 1500
1500 + 400 =1900
Bob earn $1900 a month
