1 box has 100 paper cups

Multiply both parts (the "1 box" and "100 paper cups") by k to get

k boxes have a total of 100*k cups

---------------------------------------

We have 100*k cups where k is some whole number. Divide the cost (d) by the total number of cups (100k) to get . This is the cost per paper cup in dollars. In other words, it's the cost of a single cup. Again, this is in dollars

To convert to cents, we multiply by 100

(cost per cup in dollars)*100 = cost per cup in cents
(d/(100k))*100 = 100d/100k = d/k

So the cost per cup is cents
