Question

On october 7, you deposited $15 and then had a balance of $105 in your bank account. You had deposited $12 on October 5 and had withdrawn $25 on october 2. What was your bank balance on october 2 before your withdrawal?

Answer 1

work backwards: 105 + 25 - 12 - 15 = 103

$103.

Answer 2

At the end of the day on October 7th, you have $105 in your account.

there were three actions taken before that

a. a deposit of $15- +$15
b. a deposit of $12- +$12
c. a withdrawal of $25 -$25

You want to work backwards in date, so must do the opposite of each of these.

start with $105. There was a $15 deposit (increase). Opposite of +$15 is -$15, so subtract $15.

$105 - $15
$90

There was also a $12 deposit (increase). Opposite of +$12 is -$12, so subtract $12.

$90 - $12
$78

Last, there was a $25 withdrawal (decrease). Oposite of the $25 decrease (subtraction) is a $25 increase (addition), so add $25.

$78 + $25
$103

Thus, there were $103 on October 2nd before the withdrawal.

Answer 3

OK, think of every deposit as a positive number and every withdrawal as a negative number. Thus, a deposit of $5 would mean +5, and a withdrawal of $5 would mean -5.

Make a table, with two columns. The first column should be the date of the transaction, and the second column should be the amount deposited or withdrawn.

It should look like this.

Date | Amount
--------------------
Oct 7| +15
Oct 5| +12
Oct 2| -25

Add up the three amounts. (+15) + (+12) + (-25) = +2

That number (+$2) is the difference between the amount you started with on Oct 2 and the amount you ended with on October 7.

The amount you ended up with on Oct 7 is $105. 105+ 2 = 107. Your balance on Oct 2 before your withdrawal was $107.

Answer 4

Think of this one like a checkbook, but you have to work backwards...

You know your balance at the end of 10/07 was $105. To get that balance, you deposited (added) $15. So before that deposit, your balance was $90 ($105-$15).

On 10/05, you deposited $12. So before that deposit your balance was $78 ($90-$12).

On 10/02, you withdrew (subtracted) $25. So before that withdrawal your balance was $103 ($78+$25).

Therefore your balance on 10/02 before your withdrawal was $103.

Answer 5

Just work backwards. Before October 7, you must have had $105-15=$90. Before October 5, you must have had $90-12=$78. Before October 2, you must have had $78+25=$103.

Check: $103-25=$78 (October2). $78+12=$90 (October 5). $90+15=$105 (October 7).

Answer 6

Whatever the balance is on Oct 2, say $x, it must be that x - 25 + 12 + 15 = 105.

Your starting balance, withdraw $25, deposit $12, deposit $15 and you end up at $105. You only count things that go forward in time, so if the problem further said you withdrew $40 on Sept 28, that wouldn't be used at all in helping you answer the problem.

Answer 7

on october 7 before your deposit you had $90 (105-15=90)
on october 5 you had 78 (90-12=78)
then on oct 2 you had 103 (78+25=103)

Answer 8

You do the problem backwards. set the origional balance to x.

x-25+12+15=105
x+2=105
x=103

You had $103.

Answer 9

$78

Answer 10

If something is 40% smaller, you in basic terms subtract 40%. So 40% of 40 energy is sixteen: you are attempting this by applying multiplying 40 by applying 0.4. the respond would be 40 - sixteen = 24 A shorter way would in basic terms be to multiply by applying 40 by applying 0.6, because of the fact this could be a million-0.4.
