Question

Karen and two of her friends are splitting the bill for their lunch. They each got back $2 in change after the $30 lunch bill was paid. Which of the following can be used to find the amount of money each girl contributed?

Answer 1

Hmmm, hold on I am a bit confused on the wording of this question.

Answer 2

ok

Answer 3

Let's just do some eliminating,

A says that you do:\[30 \div 3 = \] and then multiply that by 2, that gives us 20, is that a logical answer?

Answer 4

no

Answer 5

d is the answer. multiply 2 by the number of girls subtract that from 30 and then divide the remaining amount by 3 and get the answer.

Answer 6

@professional_loser_

D says "add 3 to 2" not multiply.

Answer 7

oh yeah

Answer 8

@JA1 WHOOPS i read the answers wrong

Answer 9

Anyways, it is not a logical answer because that would mean each girl gave 20 for a total of 60 which is not possible. So now let's look at B.

30 - 2 = 28
28/3 = ?

Answer 10

@professional_loser_ It's okay, It happens to all of us :)

Answer 11

ok

Answer 12

so it would be c, now that i read it right.

Answer 13

why do you say c @professional_loser_

Answer 14

@professional_loser_ the bill was 30 dollars and with C each girl would be paying 12 dollars which amounts to 36, not possible.

Answer 15

yeah thats what i thought

Answer 16

there are three girls. take the 2 dollars they each paid and add the up. you get six. add that to the amount of the bill and that is the total amount paid all together. then divide by the amount of girls and you get the amount each girl paid out in the beginning.

Answer 17

they each got back not paid sorry.

Answer 18

@professional_loser_

*high five*

I kept thinking that we are looking for how much the girls paid without counting the 2 dollars per girl. xD

Answer 19

@JA1 it is possible. if each girl paid 12 in the beginning and the bill is only 30 then they would only have needed to pay 10 so they each get two dollars back

Answer 20

its a.
because theres 3 girls. divide that by 30 it gives you 10. then divide it by 2 and it gives 5.

Answer 21

is that right @JA1

Answer 22

@kaylarusk no you want the amount each girl paid in the beginning.

Answer 23

@kaylarusk

Unfortunately no, see if the girls paid 5 dollars then that only adds up to 15/30, @professional_loser_ was right, it is C.

Answer 24

@JA1 do you know calculus by any chance?

Answer 25

@professional_loser_ What I know is too basic to be considered knowledge sorry.

Answer 26

oh @JA1

Answer 27

@JA1 how do you give medals?
