Question

Cody has $7. He wants to

buy at least 4 snacks. Hot
dogs (x) are $2 each.
Peanuts (y) are $1 each.
Which ordered pair is a
solution?
x + y >4
2x + y<7

Answer 1

(0,5) or (2,3)

Explanation:

One of those 2 is the answer since I came across 2 equations on my exam that had the same thing besides it was a tiny bit different. I just had this question on my exam and it passed. Hope this helped!

Note: I keep coming across the same question but worded a little differently. Next time please show the answer choices, if they have answer choices.

Answer 2

`x+y\geq 4\\\\2x+y\leq 7`

Explanation:

-The condition at least is inclusive of the lower bound.

-Given that the number of snacks must be at least 4, the number 4 essentially becomes the lower bound and is inclusive.

-Therefore, the number of snacks can be expressed as:

`x+y\geq 4`

-The amount spent on the snacks must be equal or less than the amount Cody has in hand, $7:

`2x+y\leq 7`

Hence, the correct ordered pair is:

`x+y\geq 4\\\\2x+y\leq 7`
