borishaifa [10]

Over drawn means negative.

So she is at -43.38 then withdraws ( takes out) 10.25

Now her account is at -43.38-10.25 = -53.63

She than adds 60

Her final amount is -53.63 + 60 = $6.37

Kipish [7]

Answer: A, C and E.

Step-by-step explanation:

The expressions 1/2 + 3c + 4/5 is thesame as writing 3c + 1/2 + 4/5, 1/2 + 4/5 + 3c, 4/5 + 1/2 + 3c, 3c + 1/2 + 4/5.

In all the expressions written above, the only thing that can be seen is just that the position of the numbers were alternated.

Therefore, based on the options given, the answer will be A, C, and E.
