Step-by-step explanation:

Please see attached image. Calculations are executed in black ink. Answer is highlighted in blue.

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

c - they will have the same distribution

step-by-step explanation:

this is the only one that could make sense. : )
