The salary for any given year n is

salary = 30000 + 5000n

how much money would you earn in the fifth year? would you just plug in 5 into n to get your answer?

yes

however, we have to look carefully what we mean by fifth year

so for the duration of year 1 you would earn 30000

for the duration of the 2nd year you would earn 35000

for the duration of the 3rd year you would earn 40000

for the duration of the 4th year you would earn 45000

for the duration of the 5th year you would earn 50000

notice 50000 = 30000 + 4(5000)

so I will revise my formula to say

salary = 30000 + 5000(n-1) , where n is the number of the year
