Answer:
(3, -1)
Step-by-step explanation:
Cat is out on the first day:
<span>240: 5 = 48 t </span>
<span>What remains after you take it out on day 48 t </span>
<span>240-48 = 192 t </span>
<span>Cat is out in the next </span>
<span>192 6 = 32t </span>
<span>What remains after you take it out 32 t of the day? </span>
<span>192-32 = </span>160t<span>
</span>
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
60% of 6,800 is 4,080 so they sold 4,080. 60
So since we know she saved 12% in the previous year so you would make a graph and then draw 100 squares now since 12 dosen't go into 100 evenly you would multiply 12 until you get 96% (which is multiplying 12 by 8) then her salary would be $4,200 dollars multiplied by 8 which is 33,600 dollars then to get your 4 more percent you would divide 12 by 3 which is 4 and you would also divide 4,200 by 3 which is 1,400 and add that to 33,600 dollars and her salary would be 35,000 dollars in the previous year her current year salary would be 38,000 dollars.
