Answer
Explanation:
Step1: Find number of girls who prefer French
Total students who prefer French is 15 and boys who prefer French is 8. So number of girls who prefer French is $15 - 8=7$.
Step2: Find number of boys who prefer Spanish
Total students who prefer Spanish is 45 and girls who prefer Spanish is 18. So number of boys who prefer Spanish is $45 - 18 = 27$.
Step3: Find total number of boys
Boys who prefer French is 8 and boys who prefer Spanish is 27. So total number of boys is $8+27 = 35$.
Step4: Find total number of girls
Girls who prefer French is 7 and girls who prefer Spanish is 18. So total number of girls is $7 + 18=25$.
Step5: Find difference between number of boys and girls surveyed
Total number of boys is 35 and total number of girls is 25. The difference is $35-25 = 10$.
