How many drops per minute?
There are 16 drops per ML.
1000 ML = 1 L.
1L = 1000 ML
Therefore 1.08 L = 1.08 * 1000 = 1080 ML
16 drops per ML means I ML has 16 drops.
Therefore 1080 ML has: (1080 * 16) drops.
Number of drops per min:
Since the entire process took 3 hours = 3 * 60 minutes = 180 minutes.
Therefore Number of drops per minute = Number of Drops / Time in minutes
= (1080 * 16) /(180)
= 96 drops per minute.
Y divided by x or 500 divided by 25
Since there are 2 semesters per year we have:
(1/2)(24,870 - 7,560) = $8,655
David would have to contribute $8,655 per semester.
