Question

Stephanie has \[\$152\] in the bank. She withdraws \[\$20\] . Then she deposits \[\$84\] . How do you write an additional expression to represent this situation then find the sum and explain its meaning?

Answer 1

Hint: To find the total money that Stephanie has after withdrawal and deposit, we must know the meaning of withdrawal and deposit. The term withdrawal means taking money from the bank. That is subtraction. We know that deposit means putting money into the bank. This means addition. Hence, total money in the bank $=\$152-\$20+\$84$ . We have to solve this to get the required answer.

Complete step by step solution:
We are given that total number of money that Stephanie has is \[\$152\] . She withdraws $\$20$. The term withdraw means taking money from the bank. That is subtraction. We are also given that Stephanie deposits \[\$84\] . We know that deposit means putting money into the bank. This means addition.
Hence, we can represent this problem in the following way to find the total money in the bank.
Total money in the bank $=\$152-\$20+\$84$
Let us first subtract \[\$20\] from \[\$152\] .
$\begin{align}
  & 152 \\
 & -20 \\
 & \_\_\_\_ \\
 & 132 \\
\end{align}$
We can write the total money in the bank as
Total money in the bank $=\$132+\$84$
Now, let us perform addition.
$\begin{align}
  & 132 \\
 & +84 \\
 & \_\_\_\_ \\
 & 216 \\
\end{align}$
Hence, total money in the bank is \[\$216\].

Note: Students may misunderstand the terms withdrawal and deposit. They must be careful when doing addition and subtraction. When doing subtraction, we have to subtract 20 from 512, not 512 to 20.
