George invited 65 students in his school to volunteer at a charity race. 39 of the students signed up to volunteer. what percent of the invited students signed up? [type your answer as a number.]

39 is 60% of 65.
Hope it helps!

The answer would be (c)

The question is kind of confusing. if it's asking how many variations of answers can you give. then do 4^5 for your answer.this would be something like the first question could be a and the 2nd c or first b next c etc. if you can, ask the teacher for a better confirmation of what it's asking. if i'm assuming correctly what it's asking, it's 625 different variations.
