Denise attends a book sale at her local
library each year. The library sells books
it no longer wants at a discount to the
public. She pays a fixed admission cost of
$5, plus a fixed cost for each book she
purchases.
Write a formula that describes how much
Denise spends at the book sale.
Let's let
b = cost of each book
n = number of books she buys
t = total cost of attending the book sale
Enter the correct answer.
1 am
B and N would be multiplied to find the total cost of books. 5 is added to that to represent the admission fee, which then equals the total cost of attending the book sale.
