At the local grocery store , a 16-ounce bottle of apple juice costs $3.20. what is the cost of the apple juice per ounce? do we divide $3.20 and 16?

You divide 16 by 3.20 to see the rate

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.
