Question

Furniture Assembly: At the beginning of your 8 hour shift, there were 42 units of furniture that needed assembled. The number of units N that still need to be assembled during your shift can be modeled by n(t)=-3t +42 where t is the time in hours...

1. Graph the model

2. What is a reasonable domain and range of the model?

3. How many units still need to be assembled after you have worked 5 hours of your shift?

Answer 1

I think you can graph straight line

t = 0 to t = 8 (end of shift, you still have 18 left for the next shift :(

n = 42 to n =18

-3(5) + 42 = 27

Answer 2

Thankyou Mr.Damon :D
