Answer:
43,200 serial numbers can be generated
Step-by-step explanation:
The ordering for the letters and the digits are important. For example, 012 constitutes a different serial number than 210. So we use the permutations formula to solve this question.
Permutations formula:
The number of possible permutations of x elements from a set of n elements is given by the following formula:

How many serial numbers can be generated
3 letters, from the first five of the alphabet
3 digits, from a set of 10
So

43,200 serial numbers can be generated
Since figure t is twice the size of figure s, figure t would be twice the size of s. hence the answer would be a scale factor of 2.
