The membership went up by 10%.
There are now 55 total students in the club.
The formula for calculating the percentage change is
[tex]p=\frac{N-O}{O}.100[/tex]
where p is the percent change, N is the New Value and O is the Old Value.
In this problem we are given the Old Value (50) and the percent change (10). We can substitute this into the formula and solve for N:
[tex]10=\frac{N-50}{50} .100\\10=2(N-50)\\5=N-50\\N=55[/tex]
There are now 55 total students in the club.
