Question

2. Ebony’s bank balance first reached $400 on Day 4. The last day her balance was $400 was Day 8.

Answer 1

She’s wrong because balance changes are different From each other and not the same.

Answer 2

Answer:

Step-by-step explanation:

a) On day 4, her balance = $400

on day 5, her balance = $0

on day 6, her balance = $400

on day 7, her balance = $0

on day 8, her balance = $400

From the above illustration, Ebony withdraws all the money and deposits the same amount, each every other days.

c)  I do not think so, perhaps, she must have been doing that previously, between day 4 and day 8, but have changed her way of withdrawals and savings between day 8 and day 12.
