10. Explain 3A
Write an equation in standard form to model the linear situation.
A tank is filling up with water at a rate of 3 gallons per minute. The tank already had 3 gallons in it before it started being filled.

11. Explain 3B
Write an equation in standard form to model the linear situation.
A hot tub filled with 440 gallons of water is being drained. After 1.5 hours, the amount of water had decreased to 320 gallons.
