Part A

Micah has a brand new boat the he takes out into the ocean that weighs approximately 48,000 pounds before any fuel is added. When fueling his boat, gasoline is pumped into the gas tank at a constant rate of 15 pounds per minute. Let t represent the elapsed time in minutes Let w represent the weight of the boat after t minutes Write an equation for w in terms of t.

Part B

Micah's cousin Eric bought the identical boat, and with a full gas tank, the boat weighs 52,000 pounds. Imagine if at the exact same time Micah's boat begins getting filled with fuel (starting with an initially empty tank), that Eric's boat with a full gas tank begins leaking fuel at a constant rate of 10 pounds per minute.

• After how many minutes do both boats weigh the same amount?

• At this time, what is the weight of each boat?
