A city's water company charges a fee of $25 a month in addition to $0.30 per every gallon used. Using the function c=0.30g+25 , where c is the total cost per month for water services and g is the number of gallons used, which of the following points on the graph accurately represents a monthly usage of 1500 gallons?(1 point) Responses (1500,-125) (1500,-125) (1500,475) (1500,475) (1500,450) (1500,450) (475,1500) (475,1500)
1 answer
To find the total cost for a monthly usage of 1500 gallons, we can use the provided function:
\[ c = 0.30g + 25 \]
Substituting \(g = 1500\) into the equation:
\[ c = 0.30(1500) + 25 \] \[ c = 450 + 25 \] \[ c = 475 \]
So, the total cost when 1500 gallons are used is $475.
Thus, the point that accurately represents a monthly usage of 1500 gallons is \((1500, 475)\).
The correct response is: (1500, 475).
