please explain both example 3 & 4

Example 3: We need a senior programmer to complete ten work assignments, each involving similar but different coding activities. Assume that the senior programmer's can do the second and third work assignments in, respectively, 42.5 and 35.4 hours. How many hours does the programmer need to perform the 6th work assignment? Bxample 4: Suppose you were required to create a reasonably detailed estimate for developing a new student information and admissions system at a local college. Your firm's programmers average 6 function points on a person-month basis. After speaking with representatives from the college, you know that their request is based on the following screen requirements: inputs (4), outputs (7), interfaces (12), queries (20), and files (16). Further, we have determined that the relative complexity of each of these functions is as follows: inputs (low), outputs (medium), interfaces (high), queries (medium), and files (medium). Using this information and the following table, calculate the number of function points for this proiect
