Answer:
Each costs $3.
Explanation:
To find out how much Brody spent on the beakers in general, you need to subtract the original amount with the new amount. So, you would do 29-2 or $27. Now that you know how much he spent, you need to know how much each costs. Of course each beaker has to cost the same so you would divide. You would do 27/9 and would come up with $3 as your answer. Hope this helped! :)
