Question: After geometry class, Bill wants to count how many lines he drew. For each shape, he drew one line per side. If he drew 12 triangles, 8 squares, and 4 pentagons, how many lines did he draw?
Answer with step-by-step thinking: For the triangles, he drew 36 lines because 12 times 3 equals 36. For the squares, he drew 32 lines because 8 times 4 equals 32. For the pentagons, he drew 20 lines because 4 times 5 equals 20. He drew 88 lines in total because 36 plus 32 plus 20 equals 88.
So the answer is 88.

Question: There are 64 seventh graders at a middle school. This is 32% of the students at the school. The sixth graders comprise 38% of the students. How many sixth graders attend middle school?
