Answer:
my money= $192.5
Natalie's money= $110
Explanation:
let my and Natalie's money be 7x and 4x respectively.
Now i gave $15 dollar to Natalie so now
my and Natalie's money will be (7x-15) and (4x+15) respectively.
now my money is 20% more than Natalie
therefore,

now calculating for x we get
x= 27.5
since, my and Natalie's money be 7x and 4x respectively
putting x=27.5
my money= $192.5
Natalie's money= $110
