Question

The table below shows the deposits (+) and withdrawals ( - ) each week for a newly opened bank account with a starting balance of $100.
DEPOSITS AND
WITHDRAWALS
Week 1+120
Week 2 -100
Week 3 +50
Week 4 P
Week 5 +200
Week 6 -100
Week 7 -25
Week 8 +50
Part A: What is the value of p if the account shows a zero balance after 4 weeks?

Answer 1

From the given table, the positive sign connote deposit while the negative sign connotes withdrawal.

If the account shows a zero balance after 4 weeks, we will take the sum of all deposits and withdrawals for the first four weeks and equate to zero as shown:

$+120+(-100)+50+p=0$

Open the parenthesis:

$+120-100+50+p=0\\20+50+p=0\\70+p=0$

Subtract 70 from both sides

$70+p-70=0-70\\p=-70$

Hence the value of p if the account shows a zero balance after 4 weeks is -70
