Area is length times width.
So you need to do:
10.5 x 9.2 = 96.6
The area of the wall is 96.6 feet square.
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 total number of fabric need is 3 and 1/2 because 2 1/4 and 1 1/4 equals 3 1/2.
Answer:
23

Answer:
27 + 28 + 29 = 84
Step-by-step explanation:
x + (x+1) + (x+2) = 84
3x + 3 = 84
84 - 3 = 81
81 / 3 = 27
