The total cost for 10 washes is $ Response area.

Answer 1

To represent the total cost for a customer who purchases \( w \) car washes, we can formulate the expression as follows:

Total Cost = One-time fee + Cost per car wash × Number of washes

This can be represented mathematically as:

\[ \text{Total Cost} = 5 + 14w \]

For the second part of your request, we need to calculate the total cost for 10 washes. We substitute \( w = 10 \) into the expression:

\[ \text{Total Cost} = 5 + 14(10) \]

Calculating that:

\[ \text{Total Cost} = 5 + 140 = 145 \]

So, the answers are:

1. Fill in the expression: 5 + 14w
2. The total cost for 10 washes is: $145
