ANSWER
![\text{ \$278.75}](https://img.qammunity.org/qa-images/2023/formulas/mathematics/college/9d07p5xcwhzc8e7k2mn8.png)
Step-by-step explanation
We have that Sammi has $125.75 in her account and deposits (adds) $25.50 every month for 6 months.
To find how much is there after 6 months, first, find out how much she added to the account and then add that to the initial amount that was there.
After 6 months she deposited:
![\begin{gathered} 6\cdot25.50 \\ \text{ \$153} \end{gathered}](https://img.qammunity.org/qa-images/2023/formulas/mathematics/college/fqwtz2qr0cfotterju9e.png)
Now, add that to the initial amount there:
![\begin{gathered} 125.75+153 \\ \text{ \$278.75} \end{gathered}](https://img.qammunity.org/qa-images/2023/formulas/mathematics/college/49xvkaag8idwgi4tndk2.png)
That is the amount in the account at the end of 6 months.
