Anne is drawing pictures. She has 12 markers and she notices that each one lasts for about 1.5 drawings. If she has already made 8 drawings, how many more can she make before she runs out of markers? Let's think first. Chain of thought:
She can make 18 drawings in total because 12 x 1.5 = 18. She can make ten more because 18 - 8 = 10.
Therefore, the answer is 10.
