Amanufacturing plant earned $80 per man hour of labor when it opened. each year, the plant earns an additional 5% per man hour. write a function that gives the amount a(t) that the plant earns per man hour (t) years after it open.

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

third choice down

step-by-step explanation:

the first inequality is based on the number of adults and campers, and the second inequality is based on the cost of feeding both the adult and the camper.

we know that there is room for 525 people max.   it's ok to have less than 525, but it's not ok to have more than 525, so the inequality is less than or equal to.   the number combination of adults (x) and campers (y) cannot exceed this 525 max.   therefore:

x + y ≤ 525

now we talk about cost.   it costs $9 to feed one adult, so depending upon the number of adults you have (x) depends upon how much it will cost to feed that number of adults.   same with the campers, who cost $5 to feed.   the adults can be represented by 9x and the campers can be represented by 5y.   since the budget cannot exceed 1,200, the second inequality is:

9x + 5y ≤ 1200
