So for this, the equation is going to be [tex] S=40(W)+350 [/tex] because the additional money relies on the number of weeks that's gone by (40(W)) and she started off with 350 (+350).
To find her balance after 16 weeks, place 16 in the w placeholder and solve from there.
[tex] S=40(16)+350\\ S=640+350\\ S=990 [/tex]
In short, the equation is S = 40(W) + 350 and Nicole's balance after 16 weeks is $990.
