Part of the question is missing
Answer:
the x terms
Step-by-step explanation:
there is a +x and a -x.
x-x=0,
x will cancel out
If we say that because she bought her materials now she has -50 then she needs to make 215+50=$265 265/17=15,5 so she needs to sell 15
But if we dont take into account that she paid $50 beforehand then 215/17=12,6 so she has to sell 13 poems. Hope it helps
