Answer:
$75 - $15 - $20 = $40
Step-by-step explanation:
Given that:
Money owed by Preston to his brother = $15
Money owed by Preston to his sister = $20
Total money earned by Preston = $75
Now, the money is paid back that he owed to his sister and brother.
To find:
The expression to represent the amount of money left with Preston after clearing all his dues?
Solution:
Once Preston pays back the money that he owed to his brother and sister, he will not have all $75 left with him.
He will have lesser amount of money.
Money left with Preston = Total money earned by Preston - Money owed to brother - Money owed to sister
Putting the values given as per the question statement, we get:
Money left with Preston = $75 - $15 - $20 = $40
Therefore, the expression to represent the amount of money left with Preston =<em> $75 - $15 - $20 = $40</em>
