Question 294015
Use an inequality and the five-step process to solve the problem. 
A bag of marbles has twice as many blue marbles as green marbles, and the bag has at least 33 marbles in it. At least how many green marbles does it have?
------------------
b = 2g
g + b >= 33
-------------------
Substitute for "b" and solve for "g":
g + 2g >= 33
3g >= 33
green >= 11 marbles
