Question

Determine whether you need an estimate or an exact answer. Then solve.

Addison paid \(1.29 for gum and \)0.89 for a package of notebook paper. She gave the cashier a \(5 bill. If the tax was \)0.14, how much change should Addison receive?

Step-by-Step Solution

Answer

Addison should receive 2.68 dollars.

Step 1. Apply the concept of addition and subtraction to receive change.

To calculate the changing price, add all amount paid by a person for his/her items and subtract it from the total amount that he/she gave to the cashier.

Step 1. Calculate the total amount paid by Addison for her items.

$\begin{array}{l}\text{Total price }P=\text{Paid for gum}+\text{Paid for package of notebooks}+\text{Tax}\\ P=1.29+0.89+0.14\\ P=2.32\end{array}$

Step 2. Calculate the total amount should Addison receive.

$\begin{array}{l}\text{Change}=\text{Amount given to the cashier }-\text{Total amount paid for items}\\ c=5-2.32\\ c=2.68\end{array}$

Therefore, Addison should receive 2.68 dollars.
