Answer:
1. $3,960,000
2. $3,840,000
3. Sell the logs.
Step-by-step explanation:
The questions are incomplete:
<em>1. What is the contribution to income from selling the logs for log cabin construction?</em>
<em>2. What is the contribution to income from processing the logs into lumber?</em>
<em>3. Should Jack’s continue to sell the logs or process them further into lumber?</em>
1. The contribution income is the total income generated by the sales of the rough logs. Each one contributes with $495.
Contribution to income (log cabin construction) = $495*8,000 = $3,960,000
2. In this case, we have to calculate what is the profit after processing each board, then multypling by the amount of boards per log and lastly multiplying by the total amoun of logs.
Contribution to income (processed board) = $(0.75-0.15)*800*8000
Contribution to income (processed board) = $0.6*800*8000
Contribution to income (processed board) = $480*8000 = $3,840,000
3. Jack should continue to sell logs for cabin construction because the profit per log is higher than for the processed board ($495/log versus $480/log).
Answer:
D - The elevator traveled upward at a rate of 2(2/5) feet per second.
Step-by-step explanation:
Okay, this is almost like kinematics, which deals with physics.
Here are your given values:
Position 1 = 70ft [down]
Position 2 = 10ft [down]
Change in time (Δt - time - scalar) = 25 seconds
The equation for displacement is d₂-d₁. This would be the change of position of the elevator during the 25 seconds.
So, we can use this equation to figure out the change in position.
Δd = d₂-d₁ = 10ft [down] - 70 ft [down] = 60ft [up]
The equation for velocity is Δd/Δt. This would be the rate of which the elevator travels. Velocity is simply speed but with a direction.
So, we can use this equation to solve.
v = Δd / Δt = 60 feet [up] / 25 seconds = 2.4 ft / second [up].
Now, we need to change 2.4 ft / second [up] into a fraction.
2.4 -> 2 (4/10) -> 2 (2/5)
All I am simply doing is figuring out the distance the elevator traveled and determined the direction of which the elevator traveled. Then, I divided that by the time the elevator traveled to determine its speed and the direction the elevator traveled.
