Question

A stackable storage rack holds 22 cd's and costs $21. how much would it cost to buy enough racks to hold 127 dvds

Answer 1

well...do the cd's cost the same as the dvd's....and do the storage racks hold the same amount of cd's as they do dvd's ?
Or is there an error in the question ?

Answer 2

i ment 127 cd's not dvds @texaschic101

Answer 3

proportion time
22/21 = 127/x -- (22 cd's to $21 = 127 cd's to x dollars)
cross multiply
(22)(x) = (21)(127)
22x = 2667
x = 2667/22
x = 121.227 rounds to 121.23

check...
22/21 = 127/121.23
cross multiply
(22)(121.23) = (21)(127)
2667.06 (rounds to 2667) = 2667 (correct)
It would cost $121.23 to buy a rack that holds 127 cd's
