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?

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.

  b.   the average rate of change of f(x) is less than the average rate of change of g(x).

step-by-step explanation:

since the length of the interval is the same in each case, we only need to compare the change in y-value to see which is greater.

so the change in y-value for function f is (6 )) = 9.

the table tells us

so the change in y-value for function g is (31 -1) = 30.

the change in y-value of f(x) on the interval is less than the change in y-value of g(x) on the same interval, so the average rate of change of f(x) is less than the average rate of change of g(x).
