PLs awnser all 3 questions thank you

Okay, so for the first question the answer would be B because 7% and 7/100 are the same thing!

For 11 it’s b. Give a moment to put the other answers

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.
