You need a common denominator while subtracting because really a fraction is a division problem and you cannot do 4/5-8/9 it does not make sense as for multiplication you really just multiplying everything that is why it makes sense.
According to John Locke, <u>Experience</u> is how we acquire basic knowledge.
What explains why, in many of the problems, historical data is used is; Information changes rapidly.
<h3>What is the theory of John Locke?</h3>
1) John Locke's theory simply means that all knowledge comes exclusively through experience. He argues that at birth the mind is a tabula rasa, that humans fill with ideas as they experience the world through the five senses.
Thus, the missing word in the question is "Experience".
2) The reason why historical data is used in may problems is because Information changes rapidly. The information being circulated currently may be different from that circulated 100 years ago.

Answer:
Price of advance ticket: 15$
Price of same-day ticket: $40
Step-by-step explanation:
Let 
be the price of one advance ticket and 
the cost of one same day ticket.
We know that the combined cost of one advance ticket and one same-day ticket is $55, so
equation (1)
We also know that 20 advance tickets and 35 same-day tickets cost $1700, so
equation (2)
Now, let's solve our system of equations step-by-step:
step 1. Solve for in equation (1)
equation (3)
step 2. Replace equation (3) in equation (2)
equation (4)
step 3. Replace equation (4) in equation (3)
We can conclude that the price of one advance ticket is $15 and the price of one same-day ticket is $40.
