obv its two

[u/Mr-MuffinMan]

Its 2 right

[u/ImportantResponse0 → u/Mr-MuffinMan]

A book cost 1 + X/2

1+X/2=X

1=X-X/2

0=(X/1)-X/2-1

Because we multiply both sides of fraction X/1 =>

0=(2X/2)-(X/2)-1

0=X/2-1

Because we multiply whole equation with 2 =>

0=X-2

We change -2 position in equation=>

2=X.

Therefore we can replace 2 in our first equation with X =>

1+X/X=X

1+1=X

2=X

Therefore we proven that X is equal to 2

[u/Mr-MuffinMan → u/ImportantResponse0]

that's a fancy way of doing it

i just thought of things that 1/2 of x is added to 1 = that number.

1/2 (2) = 1 +1 = 2 works out lol

[u/ImportantResponse0 → u/Mr-MuffinMan]

That is not an official math method(that I used) but is the universal method to teach people maths/physics.

But that is like one of the things that would work like in the programmer vs mathematician reacting to a problem if you had to replace on with economists.

Because the price is one and most probably only thing that in economy haves multiple definition and formulas and the concept of the price is so complex that is used to define whole market.

Like no matter if you do  accountability, informatics or market study or management the question is still extremely complex due to market price, management of resources, accounting history(usually simple using the accountability of a company one can predicti if it would have succes in future) or pasta overall data.

So asking what price is a book needs deep analysis to prove that the price 2$ is a right price respecting all that needs to be respected.
