Answer:
In December, Zalma will have $480.
Step-by-step explanation:
The time from March to October is 7 months. In those 7 months, she gains $280. So every month, her investment gains $40.

answer
z = 100
opposite angles
when inscribed in a circle, the opposite angles of a quadrilateral add up to 180
so z + 80 = 180 and y + 120 = 180
solve for z
z + 80 = 180
z = 180 - 80
z = 100
