Question

A pharmacy claims that the average medication costs $32 but it could differ as much as $8. Write and solve an absolute value inequality to determine the range of medication costs at this pharmacy.

|x − 32| ≥ 8; The medication costs range from $24 to $40
|x − 32| ≥ 8; The medications cost less than $24 or greater than $40.
|x − 32| ≤ 8; The medication costs range from $24 to $40
|x − 32| ≤8; The medications cost less than $24 or greater than $40.

Answer 2

First identify the key words....we see that it says `costs $32 but it could differ as much as $8.`The keyword here is `as much as` which would be \(\large{\le}\).

Answer 3

ok

Answer 4

so thats greater than or equal to right?

Answer 5

well it would actually be `less than or equal to`.

Answer 6

oh i get those confused

Answer 7

Now to find x we would split this into two equation with the outcome a negative and a positive...

\(\huge\bf{x-32 \le 8}\)

\(\huge\bf{x -32 \le -8}\)

Simplify the two.

Answer 8

Im sorry but I have to go :( maybe @3mar or @StudyGurl14 can help :)

Answer 9

The process is suppose to be typed as...

\(\huge\bf{-8 \le x-32 \le 8}\)

Sorry I typed it wrong

Answer 10

\[X \le 40\]

Answer 11

how do i solve that?

Answer 12

@3mar this is the question but i have to go for dinner Can we finish this tomorrow?

Where are you stuck?

Answer 21

I think its B but im unsure

Answer 22

Ok

Answer 23

am i right?

Answer 24

Let me check

Answer 25

k

Answer 26

It would be D.
This is because the difference in the cost doesn't exceed 8$, which means the cost difference is less or equal to 8

Answer 27

Did you get it?

Answer 28

my 10 min is up!

Answer 29

Actually it would be C.....You would simplify the expression by adding 32 to each side....

\(\huge\bf{24 \le x \le 40}\)

`The medication costs range from $24 to $40`

Answer 30

ok sorry

Answer 31

No its alright its best to know :)

Answer 32

i need help with bio
