An employee's salary, S(na), in dollars, at a company is a function of the number of years, n, that the employee has worked at the company. The relationship between n and S(12) is shown in the table below.

44,100
46,305
Which of the following equations represents an explicit formula for S(ra)?
O S(n)= 40, 000(1.05)"
O S(n)= 40, 000+1.05a
O S(n)= 40, 000(1.05)" 1
OS(12)=40,000+ 1.05(n-1)
