The cost of the 6 books if you buy the set is $11.75 less.
The given parameters:
- <em>Total number of books, n = 6</em>
- <em>Cost of the books, c = $241.25</em>
- <em>Cost of one book, = $38.25</em>
The total cost of the 6 books when bought separately is calculated as follows;
Cost = 6 x $38.25
Cost = $229.5
The difference in price is calculated as follows;
= $241.25 - $229.5
= $11.75
Thus, the cost of the 6 books if you buy the set is $11.75 less.
