Question
Hey, Scott!
I have an extra credit word problem I would appreciate some help with...here it is:

If a faucet drips at the rate of a drop every 2 seconds, and it takes 575 drops to fill a 100-mL bottle,how many liters of water are wasted in a week? (round your answers to the nearest liter)

Think you can do it? Hope so!

Sincerely,
Timothy

Answer
To get 575 drops at one drop every 2 secondds would be 1150 seconds.
This is the amount of time to fill a 100 mL bottle.

Now 1150 seconds is the same as 19 1/6 minutes.

In a week, there are 7*24*60 minutes, and that is 10,080 minutes.

If you compute 10080/(19 1/6), that is the same as 10080/(115/6),
which is the same as 2016/(23/6) = 12096/23 = almost 526 liters.

To be exact, it is 525.9130435 liters.
