Answer:
![19n+80\geq 289](https://tex.z-dn.net/?f=19n%2B80%5Cgeq%20289)
Step-by-step explanation:
Let n represent number of hours that Corinna works at museum.
We have been given that Corinna work at the museum where she earns $19 per hour. So amount earned in n hours would be
.
We are also told that Corinna has $80. So total amount of money that Corinna has in n hours would be
.
Since she wants to have a total of at-least $289, so amount saved in n hours should be greater than or equal to 289. We can represent this information in an equation as:
Therefore, the inequality
shows the number of hours, n, Corinna must work so that she has a total of at-least $289.
