To find the total cost for a monthly usage of 1,200 gallons, we can substitute x=1,200 into the given function:

c = 0.25x + 20

c = 0.25(1,200) + 20

c = 300 + 20

c = 320

Therefore, the total cost per month for a usage of 1,200 gallons is $320.

The point on the graph that accurately represents a monthly usage of 1,200 gallons is (1,200, 320).
