I would use the starting position, sea level as zero. Then I would convert all those minutes to hours so the answer is an integer and not a decimal.
60 min * (-10 ft / 212 min) = -2.83 ft/hr
round to integer = -3 ft/hr

Hope you could get an idea from here.
Doubt clarification - use comment section.

EXPLANATION
Original cost is $10
Total discount 50+20=70
So original cost *70/100
=10*70/100
=$3
Sales tax =$3+(10.1%*$10)
=$3+$1.01
=$4.01
Therefore 4.01 is the final cost of the item
