Question

Cars and trucks are the most popular vehicles. Last year, the number of cars sold was 39,000 more than three times the number of trucks sold. There were 216,000 cars sold last year. Write an equation that can be used to find the number of trucks, t, sold last year.

Answer 1

Let \( t \) be the number of trucks sold last year. According to the problem, the number of cars sold was 39,000 more than three times the number of trucks sold. We also know that 216,000 cars were sold last year. We can express this relationship with the following equation:

\[
216,000 = 3t + 39,000
\]

This equation represents the scenario described in the problem.
