Answer is 4,320 dollars because once you do 5*86400 you move the decimal to the left two times since each ml is 0.05. Giving you $4,320
gives the result in decimals. If you want percents, you could multiply the result by 100.
We did this same kind of problem in school. All we did was divide the those 2 numbers to figure out the unit price. So, 20/5 = 4 $ per CD.
Answer:
The answer is .393. Hope this helps.
