Question

Savannah had 400 chocolate chips. She saved x chips for a garnish, and mixed the rest of the chocolate chips evenly into 3 pans of brownies.How many chocolate chips were in each pan of brownies?Write your answer as an expression.

Answer 1

Total chocolate chips Savannah had = 400

Number of chocolate chips she saved for garnishing =$x$

Number of chocolate chips remain = $400 -x$

Number of brownie pans = 3

Chocolate chips were spread evenly in 3 pans,

Chocolate chips were in each pan of brownies = $\frac{400 - x}{3}$

Answer 2

Given:

• There are 400 chocolate chips in total
• x chips are saved for garnish
• The rest are mixed into 3 pans

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

$\frac{400-x}{3}$

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

$\frac{400-x}{3}$

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