Brewster collected 100 pounds of aluminum cans to recycle.  He plans to collect an additional 25 pounds each week.  Write and graph the equation for the total pounds, P, of aluminum cans after w weeks. 

• P = 125w
• P = 100 + 25w
• P = 100w + 25
• P = 100 + 25

The water level of a river is 34 feet and that it is receding (decreasing) at a rate of 0.5 foot per day.  Write an equation for the water level, L, after d days.

• L = 34 + 0.5d
• L = 34 - 0.5d
• L = 0.5 + 34d
• L = 0.5 - 34d
