85w + 350 ≥ 715
This is because you initially have 350 already, so that number shouldn't be altered. W represents the weeks, and since you get 85 per week, 85w would represent the end amount after a set amount of weeks.
Add that to the initial amount of 350.
It also states that you need at least 715, so you can have more. ≤ would represent less than or equal to, making any with that the incorrect answer.
Hope this helps!
Answer:
C. [tex]85w+350\geq 715[/tex]
Step-by-step explanation:
Let w be the number of weeks.
We have been given that you decide to save an additional $85 per week, so the money saved in w weeks will be equal to 85w.
We are also told that you have already saved $350. This means that the total money saved in w weeks will be [tex]85w+350[/tex].
Since you need at least $715 to go on a trip to Arizona. This means that the total money saved in w weeks should be greater than or equal to 715. We can represent this information in an equality as:
[tex]85w+350\geq 715[/tex]
Therefore, the inequality [tex]85w+350\geq 715[/tex] shows the number of weeks, w, you need to save to be able to go on the trip and option C is the correct choice.
