The total cost for 10 washes is $Response area.

Answer 1

To create the expression for the total cost of the car washes, we'll consider both the one-time fee and the cost per car wash. The total cost \( C \) can be expressed as:

\[ C = 5 + 14w \]

Where:

• \( 5 \) is the one-time fee,
• \( 14 \) is the cost per car wash, and
• \( w \) is the number of car washes purchased.

Now, to find the total cost for 10 washes, we will substitute \( w \) with 10:

\[ C = 5 + 14(10) = 5 + 140 = 145 \]

So, the expression to fill in is:

Response area for the expression: 5 + 14w

And the total cost for 10 washes:

Response area: $145
