Answer:

I think A.

Step-by-step explanation:

[tex]650 + 35w > 825 + 15w[/tex], option A is correct.

----------------------------

To solve this question, we build a equality for Molly's savings and for Lynn's savings. Then, we compare them with the inequality.

-----------------------------

Molly:

  • Already has $650.
  • Each week, she adds $35.

After w weeks, her amount will be of:

[tex]M(w) = 650 + 35w[/tex]

-----------------------------

Lynn:

  • Already has $825.
  • Each week, she adds $15.

After w weeks, her amount will be of:

[tex]L(w) = 825 + 15w[/tex]

-----------------------------

Which inequality could they use to determine how many weeks, w, it will take for Molly's savings to  exceed Lynn's savings?

This is w for which:

[tex]M(w) > L(w)[/tex]

Thus:

[tex]650 + 35w > 825 + 15w[/tex], option A is correct.
