The expression for the price Samantha paid for the candies is mc/n dollars.
We know that an expression, often known as a mathematical expression, is a finite collection of symbols that are well-formed in accordance with context-dependent principles.
Given that the number of candy that Samantha bought is m.
There are n candies in 1 pound.
i.e. 1 candy in 1/n pounds.
Then m candies in m/n pounds.
Also given that each pound costs c dollars.
So, m/n pound costs (m/n)*c dollars i.e. mc/n dollars.
We can conclude that the expression for the price Samantha paid for the candies is mc/n dollars.
