Answer
Linear equation: 55+8(x)=y
Volume in the sink after 25 min= 255 gallons
Step-by-step explanation:
The amount at the beggining is 55 gallons and is not changing
the water filling the tank is changing increasing 8 gallons per minute
the independent variable is the minutes and we can represented with the x
the dependent variable is the amount at the end of the minutes and we can represented with the y
The linear equation is 55+8x=y
With this equation we can find the volume after 25 minutes
=55+8*25
=255
