Question 1194719
<font color=black size=3>
t = number of minutes
This is some nonnegative real number.


The tank leaks at a rate of 4 gallons per minute. 
After t minutes elapse, the tank has lost a total of 4t gallons.


Example: 
If t = 2 minutes go by, then the tank has lost 4t = 4*2 = 8 gallons.


We subtract this amount (4t gallons) from the starting amount (200 gallons)


<font color=red>200 - 4t</font> represents how much is left in the tank.


Going back to the previous example
If t = 2, then 
200-4t = 200-4*2 = 200 - 8 = 192 gallons are left


Answer: <font color=red>Choice B) g(t) = 200 - 4t</font>
