Melissa bought 18 cupcakes and 2 gallons of fruit punch for her valentine party. if the cupcakes cost .33 each and the punch costs 2.78 a gallon estimated the cost of the fruit punch?

$5.6 for 2 gallons of Fruit Punch. 

Well if each gallon is $2.78 then the cost should be $5.56 

I hope this helps :3

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
