• A. 240
• B. 180
• C. 150
• D. 25

Correct Answer: C

Explanation:

C

The question asks for the predicted number of females in the school who plan to travel based on the table. To calculate this, find the percent of the students surveyed who are females planning to travel and multiply that percent by the total population. There are 25 females who plan to travel out of 200 total students surveyed, so the percent is × 100 = 12.5% of the students are female and plan to travel. There are 1,200 students in the school, so there would be × 1,200 = 150 females in the school who plan to travel. The correct answer is (C).
