Question

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, plus $3 for each book she decides to purchase.

Write a formula that describes how much Denise spends at the book sale.

a = cost of admission
n = number of books she buys
t = total cost of attending the book sale

Answer 1

The answer is t=a+(nx3)

Answer 2

t = a +( n×3 )

Explanation:

Denise attends a book sale at her local Library each year.

She pays a fixed admission fee and $3.00 for each book she decides to purchase.

To determine Denise spends at a book sale the equation will be

t = a +( n×3 )

Where t = Total cost of attending the book sale

n = number of books she buys

a = cost of admission
