I believe the answer is C

The wording can be a bit confusing. It took me a few seconds to realize (n>1) is just telling us that n is greater than 1 and is not part of the actual problem.

To break it down we need to know how much 1 book costs, and then multiply it by the new number of books. The new number of books is represented by n-1.

so if the total of n books is $50, then 1 book is the total divded by the number of books summed to get that total, or 50 /n

Now we take the price of 1 (represented by 50/n) and multiply that by the new quantity of books n-1.

\(\frac{50}{n}* n-1\) This is the same as \(\frac{50(n-1)}{n}\) or Answer C

The total price of n (n > 1) equally priced copies of a certain book is $50. In terms of n, which of the following gives the total price of n - 1 of these copies?

A) 50(n-1)

B) 50/(n-1)

C) {50(n-1)} / n

D) 50n/(n-1)

E) 50/{n(n-1)}

I'm confused by the wording of this problem. My answer was B but its wrong. Any help is appreciated! Also, is it better to pick numbers or solve with variable for such problems?

Thanks in advance!
