Answer:
The amount that plant earns per man hour after (t) years it open is $80 .

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 ×

or, A(t) = $ 80 ×
Hence The amount that plant earns per man hour after (t) years it open is $80 . Answer
