I don't know how to get a answer from here

You just have to be patient and wait, love. I’m sure people try to answer asap.

The answers are 20,30,80,180,960,890,1230,4560. on the first row

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.
