From the instructions in the question, we have that:

-- (1)

-- (2)

Make A the subject in (1)

Substitute for A in (2)

Open Bracket

Recall that

From the question, we understand that;

(Approximated)

step-by-step explanation:

smple

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
