Answer: B. about $152
Step-by-step explanation:
Given : Karita had $138.72 in her checking account .
i.e. Original amount in bank account=$138.72
She wrote checks for $45.23 and $18.00.
Thus, amount remains in her account= [tex]138.72-18-45.23[/tex]
[tex]=138.72-(18+45.23)\\=138.72-(63.23)\\=75.49[/tex]
Therefore,amount remains in her account=$75.49
Now, she made a deposit for $75.85 into her account.
⇒Money in Karita's account=[tex]75.49+75.85=151.34\approx152[/tex]
∴The best estimate for money is in Karita's account=$152
