Answer:
-100
Step-by-step explanation:
8*-100=-800
Let $A be the cost of $q of merchandise under plan A and similarly $B under plan B.
A=120+0.80q, B=40+0.90q
When A=B, 120+0.80q=40+0.90q, 80=0.10q, q=80/0.10=$800.
So you would need to buy $800 of merchandise.
A=B=120+640=40+720=$760 for each plan.
