Let's say the cost of student tickets is x and the cost of adult tickets is y. Then:
(1) 12y + 6x = 138
(2) 5y + 11x = 100
If we rearrange equation (1) we get:
12y = 138 - 6x
Now divide each side by 12:
y = 11.5 - 0.5x
We can now substitute this into equation (2):
5(11.5 - 0.5x) + 11x = 100
57.5 - 2.5x + 11x = 100
8.5x = 42.5
x = 5, therefor the cost of a student ticket is $5.00
22.5% written as a fraction in simplest form is 9/40 . Hope i helped.
Answer: Our Cost function is discontinuous at every integer after x>10.
Step-by-step explanation:
Since we have given that
For the first 10 minutes , the service charges = $0.30
Let the number of additional minute be 't'.
Amount charge for each additional minute = $0.05
Using the greatest integer function:
So, Cost C of a call in terms of time 't' minutes would be
As we know that Greatest integer is discontinuous at every integer.
So, our Cost function is discontinuous at every integer after x>10.
Answer:
15
Step-by-step explanation:
The absolute value takes any value and makes it positive.
|15| = 15
Answer:
20
Step-by-step explanation:
To get to -10 from 5 you have to subtract 15
to get to 20 from -10 you have to add 30
Repeat that process until you get to the 6th term.
5 (1st term)
5 - 15 = -10 (2nd term)
-10 + 30 = 20 (3rd term)
20 - 15 = 5 (4th term)
5 + 30 = 35 (5th term)
35 - 15 = 20 (6th term)
