What best explains if quadrilateral wxyz can be a parallelogram

a parallelogram is a quadrilateral, and its only requirement is that both pairs of opposite sides be parallel, they may be slanted or sideways  or long or short, but so long the opposite sides are parallel, it's a parallelogram.

the inequality is:

250c+180g≥950

step-by-step explanation:

let c denotes the number of days in a week   miyoko worked as a cryptographer.

and g denotes the number of days in a week she works as a geologist.

now we are given that she earns $250 for every day she works as a cryptographer,and earns $180 for every day she works as a geologist.

now miyoko's goal is to earn more than $950 this week.

hence, the inequality could be represented as:

250c+180g≥950
