Answer:
I think the answer is 21 students
Step-by-step explanation:
I think it's 21 students because it said twice as much girls which is telling us to multiply 7 by 2 or 7 plus 2 and in this case the product/sum would be 14, and now we add 7 boys by 14 girls and that will be 21 students altogether.
