Hey there! I'm happy to help!
We'll call our weeks w and call our total savings s.
We have an initial $85 and then we add 7 every week. This means that we will be adding 7 for every week, so we will put this in our equation as 7w.
Therefore, our equation would be s=7w+85
Now, we plug in 8 for our w value to see how much money she will have after 8 weeks.
s=7(8)+85
s=56+85
s=141
Therefore, Aubrey will have saved $141 after 8 weeks.
I hope that this helps! Have a wonderful day! :D
