Answer:
A. 10$
B. 5 days
Explanation:
A. If you start with -15 in it and deposit 5$ a day for 5 days then an equation would be, -15+(5x5)=-15+25=10, after 5 days you will have 10$
B. If you have 10$ and deposit 2 per day then you will end up with 0$ after 5 days, here is an equation for this problem, 10/2=5, so the answer is 5 days
Hope this helps, have a nice day/evening
