Answer 2

Answer:

According to your we have to find the cost of 18 books, if cost of 16 books is 300.

Solution

Cost of 16 books = 300

Then we must find cost of one book by dividing total cost by number of books, then we will multiply cost of one book by total number of books i.e. 18

Cost of 16 books = 300

Cost of 1 book = 300/16 = 18.75

So, Cost of 18 books = 18.75 × 18 = 337.5
