Question

A notebook costs d dollars in a store. Nenna bought 8 notebooks and she received a $3 discount from the store.
Write an algebraic expression describing
Nenna's total bill at the store.

Answer 1

To express Nenna's total bill at the store algebraically, we can follow these steps:

1. Calculate the total cost of the 8 notebooks without the discount:
\[
8d
\]
where \(d\) is the cost of one notebook.

2. Subtract the $3 discount from the total cost:
\[
8d - 3
\]

Thus, the algebraic expression for Nenna's total bill at the store is:
\[
8d - 3
\]
