Best of luck!
Since it is stated that the machine he bought only predict about 80%. Thus, about 20% are still possible that there are oils in the land that he owned.
In a 100% value = 80% were the 0 possibillites detected by the machine and 20% are still the possibility that it has an oil.
=> 80% = 0.80
=> 20% = 0.20
In the given choices. letter B has the closest value to the 20% that we expected.
Thus, let's have B as an answer.

Step-by-step explanation:
2x + 5 = 19; X = 7: Correct
2(7) + 5 = 19
14+5=19
3+x+2-x=16; x=3 : Incorrect
3+3+2-3=16
6+2-3=16
7-3=16
4=16
x+2/5=2; x = 8: incorrect
8+2/5=2
x= 8/5
6 = 2x -8; x = 7: correct
6 = 2(7) -8
6 = 14-8
14 =1/3x+5; x = 18: Incorrect
14 = 18/3+5
14 = 6+5
The answer is 121 because 180 - 59 = 121
