An earthquake strikes and an isolated area is without food or water. Three crews arrive. One can dispense needed supplies in 60 hours, a second in 30 hours, and a third in 80 hours. How long will take all three crows working together to dispense food and water?

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
