Answer
Explanation:
Step1: Find number of boys who prefer popcorn
We know total students who prefer popcorn is 41 and girls who prefer popcorn is 18. So number of boys who prefer popcorn is $41 - 18=23$.
Step2: Find number of girls who prefer candy
Total number of girls is 30 and number of girls who prefer popcorn is 18. So number of girls who prefer candy is $30 - 18 = 12$.
Step3: Find total number of students who prefer candy
Number of boys who prefer candy is 22 and number of girls who prefer candy is 12. So total number of students who prefer candy is $22+12 = 34$.
Step4: Find total number of boys
Number of boys who prefer popcorn is 23 and number of boys who prefer candy is 22. So total number of boys is $23 + 22=45$.
Step5: Find difference between students who prefer popcorn and candy
Number of students who prefer popcorn is 41 and number of students who prefer candy is 34. The difference is $41-34 = 7$.

|---|---|---|---|
| Boys | 23 | 22 | 45 |
