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=0.25g+20 , where c is the total cost per month for water services and g is gallons used, how do you write the ordered pair to show the usage of 1,200 gallons? (2 points)

To write the ordered pair that shows the usage of 1,200 gallons, we need to calculate the total cost \( c \) using the function given:
\[
c = 0.25g + 20
\]
Substituting \( g = 1200 \):
\[
c = 0.25(1200) + 20
\]
\[
c = 300 + 20
\]
\[
c = 320
\]
So, the ordered pair, showing the usage of 1,200 gallons and the corresponding total cost, is:
\[
(1200, 320)
\]
This means for 1,200 gallons used, the total cost is $320.
\[
c = 0.25g + 20
\]
Substituting \( g = 1200 \):
\[
c = 0.25(1200) + 20
\]
\[
c = 300 + 20
\]
\[
c = 320
\]
So, the ordered pair, showing the usage of 1,200 gallons and the corresponding total cost, is:
\[
(1200, 320)
\]
This means for 1,200 gallons used, the total cost is $320.
