Respuesta :
The number of gallons this well will produce before it runs out is 1.789 x 10⁷ gallons.
The given parameters;
- number of barrels produced in the first day, a = 426 barrels
- decrease percent in production, = 0.1%
- 42 gallons = 1 barrel
The number of gallons this well will produce before it runs out is calculated from sum of sequence.
- the rate of the this production, r = 100% - 0.1% = 99.9% = 0.999
The sum of barrels produced is calculated as;
[tex]s_n = \frac{a}{1-r} = \frac{426}{1-0.999} = 426,000 \ barrels[/tex]
The equivalent of this barrels in gallons is calculated as;
[tex]= 426,000 \ barrels\ \times \frac{42 \ gallons}{barrel} \\\\= 1.789 \times 10^{7} \ gallons[/tex]
Thus, the number of gallons this well will produce before it runs out is 1.789 x 10⁷ gallons.
