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.

Question

the total cost for 5 car washes is =??

Answer 1

The total cost for 5 car washes can be expressed as:

\[ \text{Total Cost} = \text{one-time fee} + (\text{cost per car wash} \times \text{number of car washes}) \]

Given:

• One-time fee = $2
• Cost per car wash = $10
• Number of car washes (w) = 5

The expression would be:

\[ \text{Total Cost} = 2 + (10 \times 5) \]

Calculating it:

\[ \text{Total Cost} = 2 + 50 = 52 \]

So, the total cost for 5 car washes is $52.
