To find a point on the graph that represents a monthly usage of 1,000 gallons, we need to substitute x = 1000 into the equation c = 0.25x + 20.
c = 0.25(1000) + 20
c = 250 + 20
c = 270
Therefore, the point (1000, 270) on the graph accurately represents a monthly usage of 1,000 gallons.
The city's water company charges a fee of $20 a month in addition to a $0.25 per every gallon used. Using the function `c=0.25x+20`, where c is the total cost per month for water services and x is gallons used, which of the following points on the graph accurately represents a monthly usage of 1,000 gallons?
