Solve the problem
A sports shop sells tennis rackets in 3 different weights, 2 types of string, and 4 grip sizes. How many different rackets could they sell?
To find the number of different rackets, we multiply the number of options for each category:
Number of weights: 3
Number of string types: 2
Number of grip sizes: 4
Total number of different rackets = 3 * 2 * 4 = 24
Therefore, the sports shop could sell 24 different rackets.
