2. Ebony’s bank balance first reached $400 on Day 4. The last day her balance was $400 was Day 8.(a) Determine . Explain how you determined these amounts.
(b) Estimate . Explain how you determined these amounts.
(c) Jade said that the amount of money Ebony took out of her account each day between Day 8 and Day 12 was the same amount of money she put into her account each day between Day 0 and Day 4. Recall that Day 12 is when the balance first reached $0. Without doing any calculations, how could you show Jade why that cannot be true?
Answers
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.
Explanation:
Final answer:
The average balance from Day 4 to Day 8 was $400 because her balance remained the same in that period. The balance didn't change per day, making the estimated daily change $0. Jade's statement couldn't be true as withdrawing the same amount spent from Day 8 to Day 12 would result in negative balance.
Explanation:
The question touches on averages, and understanding bank balance trends in a period.
(a) The average daily balancefrom Day 4 to Day 8 can be determined by simply taking the balance on these days and dividing by the number of days. In this case, the balance is $400 and the number of days is 4 (Day 4 inclusive to Day 8). So her average daily balance was $400.
(b) The estimated daily balance changefrom Day 4 to Day 8 can be calculated by finding the difference between the balances on these days and dividing by the number of days. However, because her balance remained the same during this period, the change per day was $0.
(c) As for Jade's statement, it cannot be true because if the same amount was deposited from Day 0 to Day 4 to reach $400, withdrawing the same amount from Day 8 to Day 12 would not result in a $0 balance but rather in a balance of $-400, given that Ebony's balance would go into the negatives.
