Step-by-step explanation:
steps are in the pic above.
The total cost if x passengers booked reclining seats and one fifths y passengers booked twin-sharing rooms is (197x + 98y) dollars
<em><u>Solution:</u></em>
Given that,
Cost for reclining seat = $ 197
Cost for twin sharing room = $ 490
We have to find the cost if x passengers booked reclining seats and one fifths y passengers booked twin-sharing rooms
<em><u>Cost for reclining room when "x" passengers booked is:</u></em>
Cost for reclining room = $ 197x
<em><u>Cost when One fifths y passengers booked twin-sharing rooms</u></em>
Cost for twin sharing room = 
Cost for twin sharing room = 98y
<em><u>Total cost is given as:</u></em>
Total cost = Cost for reclining room "x" passengers + Cost for twin sharing room for one fifths y passengers

Thus total cost is (197x + 98y) dollars

Use first differences. You are subtracting. Difference = Subtracting.
9 - x = 4
4 - x = -1
-1 - x = -6
Find for x.
9 - x = 4
- x = 5
x = -5
Therefore the answer is B.
Proof:
9 - 5 = 4
4 - 5 = -1
-1 - 5 = -6
