Answer:

Sam has 21 dollars

the ratio is 12:21

Step-by-step explanation:

Original Ratio = 4:7

Difference of numbers = 9

Take the first number = 4x

Then the other = 7x

gives us: 7x-4x=9

Now we find a factor of 9: 3x=9

x=9/3

x = 3

Therefore the 1st number = 4x = 4(3)= 12

2nd number = 7x = 7(3)=21

Proof: 21-12=9
