Final answer:
To find the number of cars sold by Ace Motors, subtract the 6 trucks sold from the total of 15 vehicles sold, which results in 9 cars being sold.
Step-by-step explanation:
The question asks us to find out the number of cars that were sold given that a total of 15 cars and trucks were sold, and 6 of these were trucks. To find the number of cars sold, we subtract the number of trucks from the total.
Total vehicles sold = 15
Trucks sold = 6
Cars sold = Total vehicles sold - Trucks sold
Therefore, Cars sold = 15 - 6 = 9 cars.
Nine cars were sold during the promotion sale by Ace Motors.
