Summarize and show how you could use the associative and commutative properties to simplify the expression b × 3 + (2 + (- show all of your work.

So b x 3 + (2 + (-b)). First use associative property. so first multiply b x 3 you get
3b + (2 + (-b)). Then use associative property and switch 2 with 3b. So it will be 2 + (3b + (-b)). Then 2 + 2b. Thats your answer

The answer is $9.90 with rounding to the nearest tenth
