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.
