Answer:
y=−3x−10
That is the equation in slope intercept form.
Answer:
a. Based on this information, construct a linear demand equation for Yoda vs. Alien T-shirts, and hence obtain the weekly revenue R as a function of the unit price x.
- y = 640 - 80x ⇒ demand equation
- xy = - 80x² + 640x ⇒ weekly revenue
b. The university administration charges the fraternities a weekly fee of $500 for use of the Student Center. Write down the monthly profit P as a function of the unit price x, and hence determine how much the fraternities should charge to obtain the largest possible weekly profit. What is the largest possible weekly profit?
Step-by-step explanation:
first, we must determine the slope = (400 - 240) / (3 - 5) = 160 / -2 = -80
the demand equation:
y - 240 = -80 (x - 5)
y = -80x + 400 + 240
y = 640 - 80x
total weekly revenue:
xy = -80x² + 640x
xy - 500 = -80x² + 640x - 500
max. profit ⇒ x = -640 / (2 x -80) = -640 / -160 = 4
maximum weekly profit = -80($4²) + 640($4) - $500 = -$1,280 + $2,560 - $500 = $780

Answer: 33.35 Pounds for each box.
Step-by-step explanation: Well first you take the weight of the empty box, 0.98, and then the weight of the packaging material, 1.74. You add that and get 2.72. So then you take the weight of the packages and minus the wight of the packaging material. 69.42-2.72=66.7. SO then you divide that by two and your answer 33.35. I am pretty sure this is the right answer, if not then I am sorry. Hope this helps.
