Answer:
38,400 for X
25,600 for Y
Step-by-step explanation:
X got 60% of 80% of 80,000 votes, so ...
80,000·0.80·0.60 = 38,400
X got 38,400 votes.
__
Y got 40% of 80% of 80,000 votes, so ...
80,000·0.80·0.40 = 25,600
Y got 25,600 votes.
The total number of students in the maths club is 40
the number of boys is 5 less than 2 times the amount of girls
to find the number of girls and boys let the number of girls be X.
so 2X-5= the number of boy
so, X+ 2X-5=40
3X-5=40
3X=40+5
3X=45
X=45/3
X=15
the number of girls is 15
and the number of boys is 15x2-5=25 boys
