Final answer:
The dealer sold 21 trucks and 48 cars.
Step-by-step explanation:
Let x be the number of trucks sold. As per the given information, the number of cars sold is 27 more than the number of trucks sold, so the number of cars sold can be represented as (x + 27).
According to the problem, the total number of cars and trucks sold is 69.
Therefore, we can set up the equation:
Number of cars sold + Number of trucks sold = Total number of cars and trucks sold
Substituting the values, we have:
(x + 27) + x = 69
By simplifying and solving the equation, we find that x = 21.
Therefore, the dealer sold 21 trucks and (21 + 27) = 48 cars.
