Allison, brianna, and celeste went on a hike. allison brought 9 homemade
cookies and brianna brought 15 cookies she had made. celeste forgot to bring
treats, but she had $2.16. allison and brianna agreed that if the three were to
share the cookies equally, then the two of them should divide celeste's money
equitably. celeste agreed. what was the fair way to divide the money?

i don't get this at all !

Allison = $0.27

Brianna = $1.89

Step-by-step explanation:

The total cookies that the three girls have are:

Allison's cookies + Brianna's Cookies

= 9+15

=24

There is a total of 24 cookies which has to be divided between the 3.

So

Each girl gets 24/3 = 8 cookies.

Since Celeste had no cookies she will have to pay for the 8 cookies.

Allison had 9, she will give one to Celeste

Brianna had 15 out of which she will use 8 for her self and 7 will be given to Celeste.

Celeste is paying 2.16 for 8 cookies.

Price of one cookie = 2.16/8

=$0.27

So, amount that will be given to Allison = 0.27 * 1 = $0.27

Amount that will be given to Brianna = 0.27 * 7 = $1.89

step-by-step explanation:

the answer is d. (1.2, -4.7) on edgn

hope this !
