Chapter 3: Q.11 (page 166)

Find the final balance in the saving account and write a positive integer to represent each deposit and a negative integer to represent each withdrawals such that You have in a saving account. You make deposits of $$30, $ 125, $10, $ 20$ and $$65$ , you make withdrawals of $$ 75, $89, $ 143, $15$ and $$ 20$ .

The representation is $$ 500 + $ 30 + $ 125 + $ 10 + $ 20 + $ 65 - $ 75 - $ 89 - $ 143 - $ 15 - $ 20$ and the final balance is $$ 408$ .

Step by step solution

Step 1. Apply the concept of integers and mathematical operations

In this type of question, use the concept that deposits may be show in positive sign, and withdrawals may be show in negative sign and then do mathematical operations.

Step 2. Finding the equation that represents the positive and negative terms

Since,

The initial deposits is $$ 500$

The deposits in a banks are $$ 500, $ 30, $ 125, $ 10, $ 20, $ 65$ .

The withdrawals in a banks are $$ 75, $ 89, $ 143, $ 15, $ 20$ .

Now, the assign the positive sign for deposits and negative sign for withdrawals and then Make a equation combinedly,

The equation is represented by:

$$ 500 + $ 30 + $ 125 + $ 10 + $ 20 + $ 65 - $ 75 - $ 89 - $ 143 - $ 15 - $ 20$ .

Step 3. Solving the equation to get the exact amount

The expression is $$ 500 + $ 30 + $ 125 + $ 10 + $ 20 + $ 65 - $ 75 - $ 89 - $ 143 - $ 15 - $ 20$

$\begin{array}{l} = $ 500 + $ 30 + $ 125 + $ 10 + $ 20 + $ 65 - $ 75 - $ 89 - $ 143 - $ 15 - $ 20 \\ = ($ 500 + $ 30 + $ 125 + $ 10 + $ 20) - ($ 75 + $ 89 + $ 143 + $ 15 + $ 20) (O n t a k i n g' -' c o m m o n) \\ = $ 750 - $ 342 \\ = $ 408 \end{array}$
