300.50(0.07)= 21.04
300.50+21.04= 321.54 321.54x = 900.85 x = 2.8
Answer:
$85
Step-by-step explanation:
5000 x $70 = $350,000
4950 x $71 = $351,450
4900 x $72 = $352,800
etc.
Create an equation for the monthly revenue:
f(n) = (5000 - 50n) x (70 + n)
= 350000 + 5000n - 3500n - 50n²
= 350000 + 1500n - 50n²
where n is the amount the ticket price is increased from $70.
Differentiate, equal to zero and solve for n to find the value of n when the monthly revenue is at its maximum:
f'(n) = 1500 - 100n
1500 - 100n = 0
1500 = 100n
15 = n
Therefore, the maximum monthly revenue is when n = 15.
So the cost of the ticket will be 70 + n = 70 + 15 = 85
Answer:
the answer is A
Step-by-step explanation:
the Pythagorean theorem is a squared + b squared = c squared (c always being the hypotenuse and a and b being the legs. 2 (4) squared pus 10 (100) squared=104 then you would use the square root of 104. 104 does not have a whole number square so the answer is
