Help I need help I don’t understand this question both of them
Advocard [28]

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

hope this helped
