Question 1055681: If 40% of the students in Art Club were boys at beginning of the year, and in the middle of the year, 25% of the girls left, but 8 boys joined, leaving 42 students in the Art Club, what was the total amount of students to begin with? Answer by josmiceli(19441) (Show Source):
You can put this solution on YOUR website! Let = the total number
of students to begin with = number of boys at beginning
--------------------------------------- = number of
girls at beginning
25% of the girls left, so 75% are left = number of
girls remain
----------------------------------- boys joined, so there are now boys
------------------------------------ students are left, so
There were 40 students to begin with
------------------------------------
check:
40% of 40, or 16 students were boys at start
40 - 16 = 24 were girls
25% of the girls left, or 6 girls
That left 24 - 6 = 18 girls remaining
--------------------------------------
8 boys joined, making 16 + 8 = 24 boys
18 + 24 = 42 students remaining
OK
