represent the number of car washes a customer purchases.

___ w+ ___

The total cost for 10 washes is $____

Answer 1

To represent the scenario with the correct expression, we can set up the total cost \( C \) as follows:

\[ C = 14w + 5 \]

This means you charge $14 for each car wash (which is multiplied by \( w \), the number of car washes), and there's also a one-time fee of $5.

So, you fill in the expression as:

14w + 5

Now, to find the total cost for 10 washes, we substitute \( w = 10 \) into the expression.

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

Calculating that gives:

\[ C = 140 + 5 = 145 \]

So, the total cost for 10 washes is $145.
