Answer:

  10 weeks

Step-by-step explanation:

Let w represent the number of weeks Anthony will be saving. Then he wants ...

  165 + 40w = 500 +0.10×500

  40w = 385 . . . . . subtract 165 and simplify

  w = 9.625 . . . . . . divide by 40

It will take Anthony 9.625 ≈ 10 weeks to save that amount.
