Sent a picture of the solution to the problem (s).
20/9 is the answer that I got
Y would equal 12 if x were to equal 4. You can think of it as a proportion.
We know that you have 83$ in your bank account.
Okay so what is 15+8=23 So that means you get 23$ per week.
Now what is 83+23=106
106+23=129
129+23=152
152+23=175
Now that was four 23's
That means it would take 4 weeks for you to have 175 dollars in your bank account.
Hope this helped.
