Question

Math 

Answer 1

What you want to find are dollars per cup. Which can also be written as dollars/cup. Note the slash there. That means division is involved. What you want to do is take the price in dollars (12.88) and put it over the number of cups (80). Such as: 

 

12.88/80

 

Find the answer. Now you know the dollars per cup of the first coffee. Do the same for the second brand. Compare the prices/cup and whichever one is lower is your best value!
