Answer:
A. More than $ 30
B. Less than $ 25,
C. More than Susain's
D. Less than
Step-by-step explanation:
∵ The much money owned by a person has less credit balance,
Suppose a person owes x dollars then his credit balance is -$ x,
Option A :
Suppose Maria's credit balance is x so his owned amount is -x,
Since, x < - 30
⇒ -x > 30
Hence, she owned more than $ 30,
Option B :
For susain, y is credit balance and -y is owned amount,
y > - 25
⇒ -y < 25
Hence, Susain owned less than $ 25,
Option C :
George credit balance = Suain credit balance - 5
If z represents the credit balance of george,
⇒ z < y
⇒ -z > - y
Hence, George owned more than Susan,
Option D :
Let a represents the owed amount of Antonio,
a < -x - 15
-a > x + 15
Thus, the credit balance of Antonio is less than maria balance.
