Question: Can you guide me through solving this problem: Carmen has $100, Samantha has $25 more than Carmen, and Daisy has $50 more than Samantha. How much do all three girls have combined?
Answer: 
Samantha has $100+$25 = $125.
Daisy has $125+$50 = $175.
The total amount of money that the three girls have is $175+$125+$100 = $400.
