* There are 17 members in a travel group. The Venn diagram below shows members that have been to the United States, Australia, both, or neither.

7 has been to Australia

9 has not been to the united states

10 has not been to Australia

8 has been to the United States

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
