Step-by-step explanation:
First, we consider the calculation towards finding the total number of passengers who had booked the train in Florence. The main question to ask in answering this problem is
This statement can be phrase mathematically using the method of ratio and proportion as shown below
,
in which the variable is the total number of passengers who booked the train from Florence.
Now, rewriting the above ratio into the form of fractions, yields
Given that a quarter out of all reservations is from Florence, then using the same method as before to evaluate the number of passengers that had booked the train (from both Bologna and Florence).
,
where the variable denotes the total number of bookings.
Therefore, the total number of passengers that had booked the train is 200.
Now, it is stated that all passengers who booked had boarded the train from Bologna which is 150 passengers (three-quarters of total bookings). Then, 36 passengers from earlier got off in Florence, while 20 passengers boarded.
Number of passengers left when arriving Rome = 150 - 36 + 20
= 134 passengers

Given expression: 1/4 (16-12x).
Solution: We can see that 1/4 is in front of paranthesis.
That represents multiplication of 1/4 with (16-12x)
In order to 1/4 with (16-12x), we need to distribute 1/4 over (16-12x).
On distributing 1/4 over (16-12x), we get
1/4 (16-2x) = 1/4 * 16 + 1/4 * (-12x).
On multiplying 1/4*16, we get 16/4 and 1/4 * (-12x) = -12x/4.
16/4 could be simplify to 4 and -12x/4 could be simplify to -3x.
So, final answer would be 4 - 3x.
Therefore, second option is our correct option, that is 4 - 3x.
