Answer:
Amount of chocolate on each pan of brownie = (400-X)/3
Explanation:
Savanna was initially having 400 chocolate chips.
she saved X chips for garnish.
Amount of chocolate chips left = total amount of chocolate chips - amount saved for garnish. Therefore,
Amount of chocolate chips left= 400 - X
Savanna mixed the rest of the chocolate chips evenly into three pans of brownies.
Amount of chocolate chips left in each pan of brownie would be amount of chocolate chips left after saving some for garnish divided by three. Therefore,
Amount of chocolate on each pan of brownie = (400-X)/3
= 400 / 3 - X / 3
= 133.33 - X/3
