12R - 4W ≥ 400

Step-by-step explanation:

If he get R correct will get 12R points

if he get w wrong will loss 4w points

so when she answered w+ r answers she will get 12R - 4W points

12R - 4W ≥ 400

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
