Say you want to provide a certain candy for Halloween. You expect around K kids to come to your house, and each kid is to be given three pieces of candy. Each bag of candy you can buy contains N pieces of candy for P dollars. Which algebraic expression will tell you how much should you expect to have to pay (M)

Step-by-step explanation:

You expect around K kids to come to your house, and each kid is to be given three pieces of candy. This means that the total number of candies that you would buy is

3 * K = 3K

Each bag of candy you can buy contains N pieces of candy for P dollars.

Therefore,

If N pieces of candy cost $P, then

3K pieces of candy would cost $M

Therefore, the algebraic expression

to tell you how much should you expect to have to pay (M) would be

M = 3KP/N
