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We shall find the total amount of each withdrawal, that is, the sum of the amount withdrawn and the ATM charge for the transaction.
[tex]\text{ Each withdrawal=x+2=\$(x+2)}[/tex]
Step 2:
Finding the required total amount, we have:
[tex]\text{ Total amount withdrawn=7(x+2)=\$7(x+2)}[/tex][tex]\begin{gathered} 7(x+2) \\ or \\ 7x+14 \\ \text{ or} \\ 7\mleft(x\mright)+7\mleft(2\mright) \end{gathered}[/tex]
Therefore, the correct answers are: [options 2, 3, and 4]
