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 admissionn = number of books she buyst = total cost of attending the book sale

t = a +( n×3 )

Step-by-step 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

using pemdas, (order of operations) you'll see the answer is 24.
