Given that 28 glasses with orange juice are filled for a camp breakfast
Each glass holds 1 cup of juice
We need to find the number of quarts of orange juice did Rebecca use
We know that a quarts has 4 cups
We need to calculate the quarts from 28 glasses

Hello!

First you had to used apply rule -(-b)=b

Since the denominators are equal to it should be combine by the fractions.

Then add 4+2=6


Finally you had to cancel by the common factor of 3.

Hope this helps! And thank you for posting at here on Brainly. And have a great day! -Charlie :)
3 hats each is the largest amount Anthony can buy.
to get this answer i multiplied 3 friends by $5 ( amount of each hat) and got $15.
i divided that into $57 and got 3.8. So he can only afford to get each friend 3 hats each. Anthony should have $12 left
