Question

indicate all the possible values.​

Answer 1

hey mate

here is the answer....

let the number of freshmen be X

thus,

the number of juniors=50 % of x

=x/2

thus,

the number of seniors=60% of x/2

=3/5*x/2

=3x/10

given:

x+x/2+3x/10≥150

(10x+5x+3x)/10≥150

18x/10≥150

x≥1500/18

x≥500/6

x≥250/3

thus,

the number of seniors=3x/10

so,

3/10 *x ≥ 3/10 *250/3

3x/10 ≥ 25

x can be greater than 25.so it can be 25,26,...
