Answer:
The amount that plant earns per man hour after (t) years it open is $80 [tex](1.05)^{\textrm t}[/tex] .
Step-by-step explanation:
Given as :
The earning of manufacturing plant when it opened = $ 80 per man hour
The rate of plant earning per man hour = 5 %
Let The earning of plant after t years = A( t )
So,
The earning of plant after t years = initial earning × [tex](1+ \dfrac{\textrm rate}{100})^{\textrm Time}[/tex]
Or, A(t) = $ 80 × [tex](1+ \dfrac{\textrm 5}{100})^{\textrm t}[/tex]
or, A(t) = $ 80 × [tex](1.05)^{\textrm t}[/tex]
Hence The amount that plant earns per man hour after (t) years it open is $80 [tex](1.05)^{\textrm t}[/tex] . Answer
