Given:
Joining fee = $28
Fee of each event = $4
To find:
Total cost for someone to attend 4 events.
Solution:
Let the number of events be x and total fee be y.
Fee for 1 event = $4
Fee for x events = $4x
Joining fee remains constant. So, the total fee is
![y=28+4x](https://tex.z-dn.net/?f=y%3D28%2B4x)
Substitute x=4 in this equation.
![y=28+4(4)](https://tex.z-dn.net/?f=y%3D28%2B4%284%29)
![y=28+16](https://tex.z-dn.net/?f=y%3D28%2B16)
![y=44](https://tex.z-dn.net/?f=y%3D44)
Therefore, total cost of 4 events is $44.
This works out beautifully. You COULD use long division here, but since your numerator is a quadratic, your first instinct should be to try and factor it. If you factor it, it works out to be (x - 3)(x + 2). Now it just so happens that when you do that, the (x - 3) in the numerator will cancel with the (x - 3) in the denominator leaving you with one sad and lonely (x + 2) as your answer.
Answer:
I would stay direct vartation
Step-by-step explanation:
For example, if y varies directly as x, and y = 6 when x = 2, the constant of variation is k = = 3. Thus, the equation describing this direct variation is y = 3x.
Answer:
3/5x + y = 22
