A balloon is initially full of air, but then it springs a leak. Air leaks at a constant rate from the balloon. After a while the leak is patched and a pump is attached to the balloon. It is re-inflated to its original volume: Air is pumped at a constant rate that is larger than the rate of the leak. Let B denote the volume, in cubic inches, of air in the balloon after t minutes. Make a graph of B versus t from the time the balloon springs a leak until it is fully re-inflated.
