Question

Corinna has $80. She wants to buy a $289 plane ticket. She will save up her earnings from working at the museum where she earns $19 per hour. Which inequality shows the number of hours, n, Corinna must work so that she has a total of atleast $289?

Answer 1

`19n+80\geq 289`

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
`19n`.

We are also told that Corinna has $80. So total amount of money that Corinna has in n hours would be
`19n+80`.

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:

`19n+80\geq 289`

Therefore, the inequality
`19n+80\geq 289` shows the number of hours, n, Corinna must work so that she has a total of at-least $289.
