I think you intended writing #30 as his pay rise instead of #30000. I solved the problem using #30 as his annual pay rise.
Answer:
The man's initial salary was #714
Step-by-step explanation:
Extracting the key information from the question:
*** A man got a pay raise for 10 years.
*** His current salary is #1,014
*** He gets a pay raise of #30 annually.
*** We are simply required to calculate his initial salary before he started receiving pay rise.
Now, To calculate his initial salary before he started receiving pay rise, let us denote that initial salary that we are currently unaware of by "a".
Since his salary as at today is #1,014 and he has also received this pay rise of #30 for 10 years, we can calculate his initial salary before he started receiving pay rise every year with the following equation:
a + 30(10) = 1014
That is -
Initial salary + [pay rise × number of years] = current salary.
a + 30(10) = 1,014
a + 300 = 1014
a = 1014 - 300
a = #714
Therefore the man's initial salary was #714
