<PRE><B>Question 966008</B>
a local water district charges a customer a fee plus 4 cents per gallon of water consumed
 jane consumed 863 gallons of water and was charged $48.02 determine the linear equation relating the consumption to the cost
:
Find b = the fixed fee charged
863(.04) + b = 48.02
34.52 + b = 48.02
b = 48.02 - 34.52 
b = $13.50, the fixed fee
:
The equation, where x = amt of water used; y = total cost
y = .04x + 13.50</PRE>
