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!
