it can be concluded that % of the boys surveyed have enrolled in spanish.

Explanation:

Step1: Find the number of boys in French

We know that the total number of students in French is 14 and the number of girls in French is 12. So the number of boys in French is $14 - 12=2$.

Step2: Find the number of girls in German

We know that the total number of girls is 30, and the number of girls in Spanish is 15 and in French is 12. So the number of girls in German is $30-(15 + 12)=3$.

Step3: Find the total number of boys

The total number of students is 50 and the total number of girls is 30. So the total number of boys is $50 - 30=20$.

Step4: Calculate the percentage of boys in Spanish

The number of boys in Spanish is 10 and the total number of boys is 20. The percentage of boys in Spanish is $\frac{10}{20}\times100\% = 50\%$.

In the table, from top - to - bottom, left - to - right: 2, 20, 3; 50
