Final answer:
In this case, Karl still needs to give Sam $150 to make the amount he owes $0.
Step-by-step explanation:
To make the amount Karl owes Sam $0, we need to determine how much more money Karl needs to give Sam.
Let's break it down step-by-step:
- 1. Karl owes Sam a total of $250.
- 2. Karl repays Sai an unspecified amount of money.
- 3. To calculate how much more money Karl needs to give Sam, we need to subtract the amount Karl repays Sai from the total amount he owes Sam.
Let's say Karl repays Sai $100.
To find out how much more money Karl needs to give Sam, we subtract the amount repaid from the total owed:
$250 - $100 = $150
Therefore, Karl would need to give Sam an additional $150 to make the amount he owes Sam $0.
