Final answer:
Leia needs a total of 1,251 batteries to power her 417 toy cars, with each car requiring 3 batteries.
Step-by-step explanation:
To find out how many batteries Leia needs for her 417 toy cars, we must multiply the number of cars by the number of batteries required per car. In this case, each car needs 3 batteries. Therefore, we calculate the total number of batteries as follows:
- Multiply the number of toy cars by the number of batteries per car: 417 cars × 3 batteries/car = 1,251 batteries.
Leia needs a total of 1,251 batteries to power all her 417 toy cars.
