Answer:
The amount that plant earns per man hour after (t) years it open is $80 .
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 ×
Or, A(t) = $ 80 ×
or, A(t) = $ 80 ×
Hence The amount that plant earns per man hour after (t) years it open is $80 . Answer
y = - x - 3
the equation of a line in ' slope intercept form ' is
y = mx + c
where m is the slope and c the y-intercept
here m = - and c = - 3
thus y = - x - 3 is the slope- intercept equation
