At central high school, 40% of the members of the Spanish club are boys. How many members does the club have if 30 of the members are girls?

Question

directrix · Answer

If 40% of the members are boys, then 60% of the members are girls.

Note that 40% + 60% = 100% which is the entire club.

If T represents the total membership of the club, then 60% of T is equal to 30.

.6T = 30

Solve for T @AngelaB97 

Post what you get, and we'll compare answers. Okay?

.6T = 30

T = 30 divided by .6

T = 30 divided by 6/10

T = 30 times 10/6

T = 300/6

T = ?

Divide 30 by .6

I did not follow this -->0.6/30=0.40(x)
I do know that 20 is not correct for the members in the club.
We know the club has 30 girls so how could the total membership be only 20?

OMG thanks. I found that there's 20 boys and that added to 30 equals 50 total members.

directrix · Answer

Oh, okay, you found the boys. 50 total is what I got, too.
