Answer:
First, I think the right formula is:

A) We first derive the formula given above:

V'(t) represent the drain rate of the tank volume.

C) at V'(10) = 100000/60 = 1666.66 gallons/time.
because the formula V'(t) is constant so it doesn't depend of time.
6 inches of yarn make 1 bracelet.
5 feet of yarn make how many bracelets?
1 foot = 12 inches
5 feet = 12 * 5 inches = 60 inches
6 inches of yarn make 1 bracelet
60 inches of yarn make x bracelets
6/1 = 60/x
Cross multiply
6x = 60
x = 10
60 inches yarn make 10 bracelets.
