The answer's 3

Answer 2

one approach
100% = 450
38% = amount he is short amount he needs to make
let this be Y
amount earned per CD = $57
amount earned per CD * number of CD sold = amount made / to be made
let the number of CD = x then
57 x = Y

Answer 3

note that you only have one unknown x, because you already computed the value of Y

Answer 4

If he needs to earn 38% more of 450, he needs to earn .38*450=171 Each CD= (whatever, I don't remember) then you need to do 171/(whatever number each CD costs) and get 3 :)
