At c cents per pound, what is the cost of a ounces of salami? (1 pound = 16 ounces)

(A) c/a
(B) a/c
(C) ac
(D) ac/16
(E) 16c/a
IMO D Lets assume a= 32 ounces, c=2
so convert ounces into pound
32/16=2 and per pound is 2 cent then 2 pound is 2*2=4 plot these values into question and only D will give answer 4
If you like my explanation then please give me Kudos Thanks in advance

1 lbs = 16 oz
1 oz = 1/16 lbs
a oz = a/16 lbs
c is cost per pound
a/16•c=ac/16

Since a ounces is a/16 pounds, the cost of a ounces of salami is c x a/16 = ac/16.

Alternate solution:

Since 1 pound = 16 ounce, c cents per pound means c/16 cents per ounce and therefore, the cost of a ounces of salami is c/16 x a = ac/16.
