Input (x) while output (y)
Plug it into the equation
1. y = 2/2 + 1. Output = 2
2. y = 4/2 + 1 Output = 3
3. y = 7/2 + 1 output = 4.5
4. y = 9/2 + 1 Output = 5.5

Answer:
![y=kx](https://tex.z-dn.net/?f=y%3Dkx)
Step-by-step explanation:
<u><em>The question in English is</em></u>
The monthly cost in a gym, and, is proportional to the number of times the client visits the gym, what equation represents the relationship between the monthly payment and the number of visits?
we know that
A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form
or ![y=kx](https://tex.z-dn.net/?f=y%3Dkx)
k represent the constant of proportionality or slope of the linear equation
In this problem
Let
x ----> the number of times the client visits the gym in a month
y ---> the monthly cost in a gym
therefore
![y=kx](https://tex.z-dn.net/?f=y%3Dkx)
X = total people
3/8x are children......that leaves 5/8 remaining...
3/4 of remaining are men...3/4(5/8) = 15/32x are men
1/4 of remaining are women....1/4(5/8) = 5/32x are women
140 more women then children...so children - 140 = women
3/8x - 140 = 5/32x
3/8x - 5/32x = 140
12/32x - 5/32x = 140
7/32x = 140
x = 140 * 32/7
x = 4480/7
x = 640
total people is 640 <===
children : 3/8(640) = 240
men : 15/32(640) = 300
women : 5/32(640) = 100
