Answer:
N = Noel's Salary
N - 512.75 = Robert's Salary (512.75 less than Noel)
3(N-512.75) = John's Salary (3 times Robert's Salary)
Step-by-step explanation:Total Salary = 47645.25 = N + (N - 512.75) + 3(N-512.75)
47645.25 = 2N - 512.75 + 3N - 1538.25
47645.25 = 5N - 2051
49696.25 = 5N
9939.25 = N (Noel's Salary)
Robert's Salary = 9939.25 - 512.75 = 9425.50

48=12+12+12+12
48=(12+3)+(12+3)+(12+3)+(12+3)
Yes. All even numbers are composite. However digits - 2, 4, 6, and 8 - do not count, since a number must be greater than 9.
