6b + 4r represents the total cost of the rice and beans gabriel bought. if he returns 2 bags of beans and 1 bag of rice, the expression that represents the total cost after the return is (6b + 4r) – (2b + r). what is this expression after simplifying?

Despite all the information you are given, all it is asking you to do is combine like terms. When there is a - outside the parentheses, you multiply everything inside of it by -1 (- represents a -1), so distribute the -1 to the terms:

6b + 4r - 2b - r

4b + 3r

As it is only asking for an expression, this is the final answer. Therefore, the expression that represents the total cost after the return is 4b + 3r.

Hope this helps! :)
