Question

Which of the following expressions could represent the total amount withdrawn from Brandon’s checking account during the time period from these ATM transactions.

Answer 1

The Solution:

Given:

Each withdrawal by Brandon = $x

ATM charge per transaction = $2

Required:

To find an expression for Brandon's total withdrawal if he withdraws the same amount once a week for 7 weeks.

Step 1:

We shall find the total amount of each withdrawal, that is, the sum of the amount withdrawn and the ATM charge for the transaction.

$\text{ Each withdrawal=x+2=\ (x+2)}$

Step 2:

Finding the required total amount, we have:

$\text{ Total amount withdrawn=7(x+2)=\ 7(x+2)}$$\begin{gathered} 7(x+2) \\ or \\ 7x+14 \\ \text{ or} \\ 7\mleft(x\mright)+7\mleft(2\mright) \end{gathered}$

Therefore, the correct answers are: [options 2, 3, and 4]
