21. carrie withdraws $10 from her account each day for 7 days.
a. what integer represents the total change in her account balance?
b. her bank account had $120 in it before she began withdrawing money. what is her
balance after withdrawing the money for 7 days?

a.70. b.50

Step-by-step explanation:

If Cartie takes $10 from her account for 7 days she would have taken $70 out.

Next we look at the net problem it is asking us how much is left we already know from the equation above that we need to subtract 70 from 120We now have both answers A. being that she would have taken $70 in total out of her account and B. being that she would have $50 left in her account.
