Question

There were 45 cars on the highway this morning. If c amount of cars turned off the highway, write an expression that represents the amount of cars still on the highway.

Answer 1

To represent the amount of cars still on the highway after \( c \) cars turned off, you can use the expression:

\[
45 - c
\]

This expression indicates that you start with 45 cars and subtract the number of cars \( c \) that have turned off the highway.
