Each complete cleaning requires 6 drops of cleaner.  Let's convert that to ml:
6 drops     1 ml              3 ml cleaner
----------- * ------------- = ------------------- = 0.3 ml cleaner per cleaning
                 20 drops      10 cleanings
Recall that 1 bottle contains 30 ml cleaning fluid.
How many cleanings is one bottle of fluid good for?
1 bottle       0.3 ml
----------- = -----------   => x = 100 cleanings/bottle
      x            30 ml

Answer:
Step-by-step explanation:
depreciation for three years = 32000 - 24500 = $ 7500
depreciation per year = 7500/3 = $ 2500
depreciation % = (2500/32000)*100 = 7.81%
Value of truck after n years = 32000 * (7.81%)*n
