Answer:
23pupils
Step-by-step explanation:
Given parameters:
Number of 18th grade boys this year = 18
Percentage decrease = 28%
Unknown:
How many 8th grade teams were there last year = ?
Solution:
Since this is a percentage decrease, ;
Number of pupils this year = Number of pupils last year - (28% x 18 )
18 + (28% x 18 ) = Number of pupils last year
Number of pupils last year = 23pupils
Let the number of boys be x
Let the number of girls be y
x＝y＋5
3y＝2x＋12
3y＝2(y＋5)＋12
y＝22
3×22＝2x＋12
x＝27
(x, y)＝(27, 22)
There are 27 boys and 22 girls.
