Question

Harriet has $25 in her savings account. She will add $5 each week and not take any money out of her account.

Which expression represents the amount of money in her savings account after x weeks?
A. 5(x+25)
B. 25(x + 5)
C. 5x + 25
D. 25x + 5

Answer 1

To find the expression that represents the amount of money in Harriet's savings account after \( x \) weeks, we start with her initial amount of $25.

Every week, she adds $5 to her savings account. Therefore, after \( x \) weeks, she adds \( 5x \) dollars to her initial $25.

Putting this together, the total amount in her savings account after \( x \) weeks can be expressed as:

\[
\text{Total amount} = \text{initial amount} + \text{amount added}
\]
\[
\text{Total amount} = 25 + 5x
\]

This can also be written as:

\[
5x + 25
\]

So, the correct expression is:

**C. 5x + 25**
