Question

Katy buys 3 dvds every two weeks. how many dvd's will she buy in 14 weeks?

Answer 1

21 DVDS because if u do 7x2=14 so u then do the same to the 3 DVDS which makes 21 because u again do 3x7=21

Answer 2

Answer:

21 dvds

Step-by-step explanation:

Set up a proportion in terms of DVDs to weeks and solve.

3/2 = x/14

(2)(x) = (3)(14)

2x = 42

x = 21

Therefore, Katy will buy 21 DVDs in 14 weeks.
