Carlos has 42 books he wants to store on shelves. Each book is
1 3/4 inches thick. He can buy 3-foot-long shelves for $27.99 each. How much will it cost to shelve the books?

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
