Answer:
a) $50,880
b) $48
c) 1060
Step-by-step explanation:
a)
-320x^2 + 1920x + 48000 = 0
This is a parabola that opens downward. It has a maximum value. The maximum value occurs at x = -b/(2a)
x = -b/(2a) = (-1920)/(2(-320)) = 1920/640 = 3
The maximum revenue, y, is the value of the function evaluated at x = 3.
f(x) = -320x^2 + 1920x + 48000
f(-3) = -320(3)^2 + 1920(3) + 48000
f(-3) = 50,880
The maximum revenue is $50,880
b)
Since maximum revenue occurs at x = 3, and since x represents the number of $4 discounts, the discount is 3 * $4 = $12. The price is $60 - $12 = $48
c)
$50,880/$48 = 1060
Answer:
the answer is B because y depends on x
X=5/2
4x7.5=12x
30=12x
X=30/12
X=5/2
Answer:
-1
Step-by-step explanation:
-3(2) = -6 + 5 = -1
A salesperson had 240,000 in sales last year.....which is 60% of the sales she had this year....
so 60% of the sales she had this year = 240,000...
0.60x = 240,000...with x being the sales she had this year
x = 240,000 / 0.60
x = 400,000 <== ur answer
