David is buying a new car. He can choose

from 11 car colors, 5 interior materials, and 7

safety features. How many different

combinations of cars could David order?

Enter the correct answer.

385 different combinations

Step-by-step explanation:

In order to find the number of different combinations when given the number of options, simply multiply all options together - almost as if you were solving for the volume of a rectangular prism.

For example, if I were given 3 different colors and 2 different interior materials, I would have 6 different combinations of cars, because 3x2 is 6.

In this case, 11x5x7 is 385!
