Look at the table showing different prices for cans of soup. Prices for Soup
Price A
Price B
Price C
$3.87 for 3
$2.38 for 2
$8.75 for 7

Which gives the prices in order, from greatest to least unit rate?
Price B, Price C, Price A
Price A, Price C, Price B
Price C, Price A, Price B
Price B, Price A, Price C

It would be price a, price c, price b because to find the unit rate you divide like: 3.87/3.

i might be wrong tho! i haven't done this in a while! lol

Best answer that i found on yahoo ok   set :   x= length of 2nd piece in cm  x- 3= length of 1st piece in cm  x-4= length of 3rd piece in cm  then since you know they all came from the 20 cm ribbon you add them together and set them equal to 20x+ x-3 +x-4 = 20  3x - 7= 20  3x= 27  x= 9  the shortest piece is the third piece which is x- 4  x-4  9-4 = 5  the length of the smallest piece is 5 cm.  the other lengths are  9 cm  6 cm
