sorry but if we put together the equation should be 144(x-0.36)= 144x - 51,84

therefore we should be able to know what is the percent change right?

Where is my mistake?
If you assume your initial price was x per candy then for 144 candies you know that your final price was 144x - 51.84.

Percentage change = 100*(Initial Price - Final Price)/(Initial Price) = 100*(144x - (144x - 51.84))/144x = 5184/144x = 36/x

As we don't know x, we can't calculate the exact percentage change here.

In a way both options are just repeating same information that you are saving 36 cents per candy but you don't know either the initial price or the final price but the delta, and hence you cannot calculate the exact percentage value here.

but what exactly is wrong with the equation I would have marked c for this after making the Same equation.

I wilder have bothered solving it to find out if its giving x or not.

I made the same mistake as you did.:lol:
These two statements say the same thing, so they can't complement each other.
