Answer:
The equation is given below as
[tex]f(t)=1.5(0.90)^t[/tex]
The function above represents an exponential function.
The general function of an exponential function is given below as
[tex]\begin{gathered} y=ab^x \\ b>1(growth),b=1+r \\ b<1(decay),b=1-r \\ \end{gathered}[/tex]
By comparing coefficients, we will have
[tex]\begin{gathered} 0.90<1(decrease\text{ over the years t\rparen} \\ 1-r=0.90 \\ r=1-0.90 \\ r=0.10 \\ r=0.10\times100 \\ r=10\% \end{gathered}[/tex]
Hence,
The final answer is
The number of employees is decreasing by 10% every year
