The answer is obviously the second one B or number two
The week would be week 5 and the amount would be $525
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:
1) The smallest is 1000, and the greatest is 9998.
2) The smallest is 1001 and the greatest is 9999.
Step-by-step explanation:
Four digit numbers:
The set of four digit numbers is: {1000, 1001, ...., 9998, 9999}
Even numbers:
End in 0, 2, 4, 6, 8
Odd numbers:
End in 1, 3, 5, 7, 9
1) the number is an even number
The smallest is 1000, and the greatest is 9998.
2)the number is an odd number
The smallest is 1001 and the greatest is 9999.
