Wrapping paper is on sale at 3 rolls for 4.25. How many rolls can Danika buy with $20? (i've been searching all around the internet for the answer but i can't seem to find one similar to the answer my teacher gave me)

Can buy 14 rolls

Step-by-step explanation:

Cost per roll:

  4.25 / 3 = 1.42 each roll

How many can buy for $20:

  1.42x = 20

  x = 14 rolls

for the points! : )

maximum area = xy = (16)(32) = 512 ft2

to maximize the area of the garden, the side of the fence parallel to the side of the house should be 32 ft long, and the other two sides should both have length 16 ft.'
