Barry arrives at the hotel each morning at 7: 00am. today he will stay late to oversee a party in the ballroom. he will leave the hotel at 1: 00am. how many hours will barry spend at the hotel today?

im pretty sure 13 hours he would spend in the hotel, 7 am to 1 am, hope this helps^^

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
