Step-by-step explanation:
Assuming that the tank is only for agricultural use, also no significant leakages then at the end of the day, the amount consumed will be equivalent to
For 5 days, the quantity reduces by 9.5*5=47.5 gallons
Therefore, the barrel would have changed by
x=4
We can use the leg rule
hyp leg
------- = -----------------
leg part
2+6 x
x 2
Using cross products
8*2 = x^2
16 =x^2
Take the square root of each side
4 =x
54
1,338,750$
1990 price was 850,000
in 2000
850,000 + 125% = 1,062,500
850,000 + 1,062,500 = 1,912,500
in 2013
1,912,500 - 30% = 573,750
1,912,500 - 573,750 = 1,338,750
