Answer: (C)
Step-by-step explanation:
The bill is $58. The first 3000 gallons cost $41 so there is a charge of $17 ($58 - $41) for the gallons used over the first 3000 gallons.
There is a charge of $1 for each 200 gallons so the additional gallons is 17 x 200 = 3400 gallons.
The total gallons used is 3000 (charged at $41) and 3400 gallons (charged at $17) which is a total of 6400 gallons.
