Problema Solution

There are 200 books on a shelf. There are 6 more fiction books than 8 times the non-fiction books. How many non-fiction books are on the shelf. Write an equation for the situation and then solve.

Answer provided by our tutors

let


f = the number of fiction books, f is integer, f>= 0

n = the number of non-fiction books, n is integer, n>=0


There are 200 books on a shelf


f + n = 200


There are 6 more fiction books than 8 times the non-fiction books


f = 8n + 6


by solving the system of equations:


f + n = 200

f = 8n + 6


we find


f = 178.44


n = 21.56
