Question

Yesterday, Julie’s bank account balance was –$10.28. She deposited some money into her account so that her balance is now $39.89. How much did she deposit into her account?
a. $50.17
b. $39.00
c. $29.72
d. $10.00

Answer 1

Julie owed $10.28 in her bank account. If you think of the number line that value is to the left of zero in the negative. So, just to get back to 0 you have to add positive 10.28. From zero her current balance is 39.89, so if you add 39.89 to zero with the 10.28, you end up with a total of $50.17 to get to her current balance.
So the answer is A.

Answer 2

10.28+39.89=50.17

hope this helps
