David is organizing a charity car wash. He plans to charge $10 per car wash as well as a one-time fee of $2 to cover supplies. Fill in the expression with the correct numbers to represent the given scenario. Let w represent the number of car washes a customer purchases.

Answer 1

To represent the total cost for a customer who purchases \( w \) car washes, you can use the following expression:

\[ \text{Total Cost} = 10w + 2 \]

In this expression:

• \( 10w \) represents the cost of the car washes, where \( w \) is the number of car washes purchased (at $10 per wash).
• \( 2 \) is the one-time fee for supplies.

So, the total cost for a customer who buys \( w \) car washes is \( 10w + 2 \).
