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.

Each pan of brownies had chips

Explanation:

Savannah originally had 400 chocolate chips

Now, she saved x chocolate chips for garnish

This means that the amount she originally had decreased by x

Savannah now has 400-x chocolate chips to use for brownies

She divided this amount evenly into three pans. This means that the amount in each pan will be equal to the amount she has now divided by 3

This means that:

Each pan got chips

Hope this helps :)
