Someone please help !!easy ! Pumpkins are on sale for $4 each, but customers can buy no more than 3 at
this price.
For pumpkins bought at the sale price, the total cost, y, is directly proportional
to the number bought, x. This function can be modeled by y = 4x.
What is the domain of the function in this situation?
A. {0, 1, 2, 3, 4, ...}
B. {0, 4, 8, 12)
C. {0, 1, 2, 3
D. All positive numbers, x>0

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
