Answer: 80.1.05^t

Step-by-step explanation: got it

Answer 2

Answer:

The amount that plant earns per man hour after (t) years it open is           $80 $(1.05)^{\textrm t}$ .

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 × $(1+ \dfrac{\textrm rate}{100})^{\textrm Time}$

Or, A(t) = $ 80 × $(1+ \dfrac{\textrm 5}{100})^{\textrm t}$

or, A(t) = $ 80 × $(1.05)^{\textrm t}$

Hence The amount that plant earns per man hour after (t) years it open is   $80 $(1.05)^{\textrm t}$ . Answer
