Extra 10, 10 is half of what she ordered so she received an extra 50%
5x’2-4x+7-4x-2
We add the two 4
5x’2-8x+7-2
5x’2-8x+5
The answer is
5x’2 -8x +5
Answer: a) Q= 5units
b) R= $75
Step-by-step explanation:
The maximum revenue is at dR/dq = 0
Revenue = price x quantity of demand = p × q
Substituting p = 30- 3q
R = (30-3q) × q
R= 30q- 3q2 (q2 = q raised to the power of 2)
dR/dq = 30- 6q = 0
6q = 30
q= 30/6= 5
q= 5 units
R = pq= 30q- 3q2
R= 30(5) - 3( 5×5)
R= 150- 75
R= $75
Goodluck...
Perpendicular lines have slopes that are opposite and reciprocal. Therefore, the line we are looking for has a -3 slope.
y= -3x+b
Now, we can substitute in the point given to find the intercept.
2= -3(4)+b
2= -12+b
b=14
Finally, put in everything we've found to finish the equation.
y= -3x+14
