Number of chocolate chips she saved for garnishing =

Number of chocolate chips remain =

Number of brownie pans = 3

Chocolate chips were spread evenly in 3 pans,

Chocolate chips were in each pan of brownies =

Given:

To Find:

The number of chocolate chips in each pan of brownies

Solution:

The expression denoting the number of chocolate chips in each of the 3 pans is

Calculation:

We are given that there are 400 chocolate chips in all. Out of these, x number of chocolate chips are for garnish.

This means, 400-x are the remaining number of chocolate chips that are to be divided and mixed into 3 pans evenly.

Therefore, using the Unitary Method, we can see that the number of choloate chips in each pan can be found by dividing the total number of chocolate chips to be put in the pans (i.e., 400-x) by the number of pans (i.e., 3).

So the required expression is

This is the number of chocolate chips in each of the 3 pans.
