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

Answer:

$19n+80\geq 289$

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 $19n$.

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.
