Title:
<h2>The revenue will be maximum for 253 passengers.</h2>
Step-by-step explanation:
Let, the number of passenger is x, which is more than 194.
In this case, the travel agency will charge [312 - (x - 194)] per passenger.

.
As x is the variable here, we can represent the revenue function by R(x). Hence,

Water cooler
holds = 50 pt of water
1 L≈1.06 qt (which is the value of US liquid quart)
1.06 qt = 2.12 pt (which is the value of US liquid pint)
So when we are calculating how many liters of water cooler holds,
divide the 50pt with 2.12pt
50pt/2.12pt = 23.6 Liters
<span>So 23.6 is the correct answer.</span>
