x/12 ----> cost of per can of soda

Cost of y cans ---> x/12 . y .100 = 25xy/3

Hence D is the correct option

number of cans and cost vary directly with each other. 12 cans cost x dollars, let y cans cost 'z' dollars.

So we have 12/x = y/z or z = xy/12 dollars
Converting to cents (1$ = 100cents)
xy/12 * 100 = 25xy/3 cents

Hence answer is D
