Answer:
After 4 months, the charges will be same.
Step-by-step explanation:
Membership charges of club one = $40
Per month charges = $40
Let,
x be the number of months
y be the total amount
y = 40x + 40
Membership charges of club two = $100
Per month charges = $25
y = 25x + 100
For equal charges, both equations will be same
40x + 40 = 25x + 100
40x - 25x = 100 - 40
15x = 60

Therefore,
After 4 months, the charges will be same.

Given
on solving this mixed fraction we get;

Now adding these fractions by same denominator method.
![-\frac{29\times3}{10\times3} +[-\frac{64\times2}{15\times2} ]\-\frac{87}{30} +[-\frac{128}{30}]\ = -\frac{215}{30}](https://tex.z-dn.net/?f=-%5Cfrac%7B29%5Ctimes3%7D%7B10%5Ctimes3%7D%20%2B%5B-%5Cfrac%7B64%5Ctimes2%7D%7B15%5Ctimes2%7D%20%5D%5C-%5Cfrac%7B87%7D%7B30%7D%20%2B%5B-%5Cfrac%7B128%7D%7B30%7D%5D%5C%20%3D%20-%5Cfrac%7B215%7D%7B30%7D)
