The area of the rectangular page is 240 square inches.
The rectangular page has a width of x inches and a length of
.
The area of printable page is 160 square inches.
The rectangular page has 2 inch margins at the top and 1 inch margins on each side.
Area of a rectangle is given by length × width.
The printable area is (x - 2) × (
- 4) = 160 square inches.
This can also be represented as:
160 = (x - 2)(
)
Answer:
The optimal price should be $10 which will result in maximum revenue.
Step-by-step explanation:
y = [5+ 0.5x] [ 300 - 30x]
y = 1500 - 150x + 150x - 15x^2
y = 1500 - 15x^2
x^2 = 1500 /15
x = ![\sqrt{100}](https://tex.z-dn.net/?f=%5Csqrt%7B100%7D)
x = 10
Answer:
1,456
Step-by-step explanation:
The sum of n terms of a geometric sequence with first term a1 and common ratio r is given by ...
Sn = a1·(r^n -1)/(r -1)
For your series with a1=4, r=3, and n=6, the sum is ...
S6 = 4·(3^6 -1)/(3 -1) = 2·728 = 1,456
Answer: The cost of adult ticket is $6.1 and that of student ticket is $2.44
<u>Step-by-step explanation:</u>
Let the cost of adult ticket be 'x' and cost of student ticket be 'y'
From the question, the equations formed are:
.....(1)
......(2)
Putting value of 'y' from equation 2 to equation 1:
![662.5=85(2.5x)+65y\\\\662.5=271.5y\\\\y=\frac{662.5}{271.5}=\$ 2.44](https://tex.z-dn.net/?f=662.5%3D85%282.5x%29%2B65y%5C%5C%5C%5C662.5%3D271.5y%5C%5C%5C%5Cy%3D%5Cfrac%7B662.5%7D%7B271.5%7D%3D%5C%24%202.44)
Now, solving for 'x', we get:
![x=2.5(2.44)=\$ 6.1](https://tex.z-dn.net/?f=x%3D2.5%282.44%29%3D%5C%24%206.1)
Hence, the cost of adult ticket is $6.1 and that of student ticket is $2.44
